Does it actually work?

ghost · 2014-03-18T07:18:59Z

This looks amazing... :P

enedil · 2014-03-18T07:19:10Z

And why would anyone want to use it?

Would you mind put the link of reference?
The link on the first discussion message got 404.

Thanks

Should have at least started by putting the check inside of a function.

Commit 8f898e9 removed the redundant reads of bInterfaceProtocol from the descriptors, but introduced a regression to devices with quirks of type QUIRK_AUDIO_FIXED_ENDPOINT, since fp->protocol is not set in setup process. As a consequence, audio streams would not get initialized, as the following logs show: [ 48.923043] setting usb interface 3:1 [ 48.923056] Creating new capture data endpoint torvalds#81 [ 48.923484] 4:3:1: cannot set freq 48000 to ep 0x81 This patch sets fp->protocol in create_fixed_stream_quirk() and resolves the regression.

Your other "joke" pull request made me laugh a bit. However, the linux kernel (particularly torvalds:master) isn't the place for this kind of humor.

The code itself is useless. For one thing, you didn't even declare facebook_login_is_correct and what it is or does, you aren't working with Facebook at all in this code. Next up, facebook_login_is_correct can't be both a function and a boolean. You only broke it all. Then there's for (;;){sleep();}, which means sleep() will run and nothing else, and that is in the kernel which is responsible for what code is running at all times, so on ACCESS DENIED the computer just hangs and freezes.

Forget about that, Linux is only the kernel. Linux by itself does not have the user interface, the authentication control, or even the core system startup/service manager. Get out of this misconception that "Linux" is the whole operating system. You're modifying the Linux kernel, the part that goes in between to manage processes and drivers, applies contexts such as privileges and filesystem locations, and generally is responsible for what code is running at all times.

The correct form of what you're trying to achieve is actually a http://linux-pam.org/Linux-PAM-html/Linux-PAM_MWG.html module for logging in with Facebook, and maybe a GDM greeter which has a discrete "Login with Facebook" option, but this retarded try with the kernel should be closed.

Is there any benefit to having this in kernel space instead of user-space?

This commit fixes the following checkpatch warnings: WARNING: externs should be avoided in .c files torvalds#80: FILE: drivers/staging/dgnc/dgnc_driver.c:80: +int dgnc_init_module(void); torvalds#81: FILE: drivers/staging/dgnc/dgnc_driver.c:81: +void dgnc_cleanup_module(void); This was caused by putting the declarations for module init and module exit fucntions on the top of the file. The fix removes these declarations plus it also corrects the type of the init/exit functions. Due to the dependency between init and exit functions the dgnc_cleanup_module had to be put first.

Looking at the canary code, I realized that every arch (except ia64, which adds some space for register spill above the stack) shares a definition of end_of_stack() that makes it the first long after the threadinfo. For stacks that grow down, this low address is correct because the stack starts at the end of the thread area and grows toward lower addresses. However, for stacks that grow up, toward higher addresses, this is wrong. (The stack actually grows away from the canary.) On these archs end_of_stack() should return the address of the last long, at the highest possible address for the stack.

This makes it impossible to use a percpu_ref to count memory objects or pages on 64bit machines as it may overflow. This forces those users to somehow aggregate the references before contributing to the percpu_ref which is often cumbersome and sometimes challenging to get the same level of performance as using the percpu_ref directly. While using ints for the percpu counters makes them pack tighter on 64bit machines, the possible gain from using ints instead of longs is extremely small compared to the overall gain from per-cpu operation. This patch makes percpu_ref based on longs so that it can be used to directly count memory objects or pages.

For IN transfers, it left the URB DMA buffer mapped until the transfer completed, then synced it, copied the data from the bounce buffer, then synced it again. Instead of that, just call usb_hcd_unmap_urb_for_dma() to unmap the buffer before starting the transfer. Then no syncing is required when doing the copy. This should also allow handling of other types of mappings besides just dma_map_single() ones. Also reduce the size of the bounce buffer allocation for Isoc endpoints to 3K, since that's the largest possible transfer size. Tested on Raspberry Pi and Altera SOCFPGA.

Up to now there were initialized 16 TX FIFOs, but we use only 8 IN endpoints, so we can split available memory for 8 FIFOs to have more memory for each one. It needed to do some small modifications in few places in code, because there was assumption that TX FIFO numbers assigned to endpoints are the same as the endpoint numbers, which is not true since we have dynamic FIFO assigning.

Changes to correct several GPIO issues: 1) The update_rule in a GPIO field definition is now ignored; a read-modify-write operation is never performed for GPIO fields. (Internally, this means that the field assembly/disassembly code is completely bypassed for GPIO.) 2) The Address parameter passed to a GPIO region handler is now the bit offset of the field from a previous Connection() operator. Thus, it becomes a "Pin Number Index" into the Connection() resource descriptor. 3) The bit_width parameter passed to a GPIO region handler is now the exact bit width of the GPIO field. Thus, it can be interpreted as "number of pins". Overall, we can now say that the region handler interface to GPIO handlers is a raw "bit/pin" addressed interface, not a byte-addressed interface like the system_memory handler interface.

This means that draining a blk-mq takes measureable wallclock time. One would think that this shouldn't matter as queue shutdown should be a rare event which takes place asynchronously w.r.t. userland. Unfortunately, SCSI probing involves synchronously setting up and then tearing down a lot of request_queues back-to-back for non-existent LUNs. This means that SCSI probing may take above ten seconds when scsi-mq is used. [ 0.949892] scsi host0: Virtio SCSI HBA [ 1.007864] scsi 0:0:0:0: Direct-Access QEMU QEMU HARDDISK 1.1.

This patch makes blk-mq initialize q->mq_usage_counter in atomic mode and switch it to percpu mode only once blk_register_queue() is reached. Note that this issue was previously worked around by 0a30288da1ae ("blk-mq, percpu_ref: implement a kludge for SCSI blk-mq stall during probe") for v3.17. The temp fix was reverted in preparation of adding persistent atomic mode to percpu_ref by 9eca80461a45 ("Revert "blk-mq, percpu_ref: implement a kludge for SCSI blk-mq stall during probe""). This patch and the prerequisite percpu_ref changes will be merged during v3.18 devel cycle.

This makes the atomic mode difficult to use for cases where a percpu_ref is used as a persistent on/off switch which may be cycled multiple times.

Similarly, percpu_ref_switch_to_atomic/percpu() allow dynamic selection of operation mode; however, currently a newly initialized percpu_ref is always in percpu mode making it impossible to avoid the latency overhead of switching to atomic mode. This patch adds @flags to percpu_ref_init() and implements the following flags. * PERCPU_REF_INIT_ATOMIC : start ref in atomic mode * PERCPU_REF_INIT_DEAD : start ref killed and drained These flags should be able to serve the above two use cases. v2: target_core_tpg.c conversion was missing.

The MAX77836 charger is almost the same as 14577 model except: - No dead-battery detection; - Support for special charger (like in MAX77693); - Support for DX over-voltage protection (like in MAX77693); - Lower values of charging current (two times lower current for slow/fast charge, much lower EOC current); - Slightly different values in ChgTyp field of STATUS2 register. On MAX14577 0x6 is reserved and 0x7 dead battery. On the MAX77836 the 0x6 means special charger and 0x7 is reserved.

However, llc_shared_mask is not released during CPU disable, which leads to an invalid sched domainCPU topology. This patch fix it by releasing the llc_shared_mask correctly during CPU disable. Yasuaki also reported that this can happen on real hardware: https://lkml.org/lkml/2014/7/22/1018 His case is here: == Here is an example on my system. My system has 4 sockets and each socket has 15 cores and HT is enabled. In this case, each core of sockes is numbered as follows: | CPU# Socket#0 | 0-14 , 60-74 Socket#1 | 15-29, 75-89 Socket#2 | 30-44, 90-104 Socket#3 | 45-59, 105-119 Then llc_shared_mask of CPU#30 has 0x3fff80000001fffc0000000. It means that last level cache of Socket#2 is shared with CPU#30-44 and 90-104. When hot-removing socket#2 and #3, each core of sockets is numbered as follows: | CPU# Socket#0 | 0-14 , 60-74 Socket#1 | 15-29, 75-89 But llc_shared_mask is not cleared. So llc_shared_mask of CPU#30 remains having 0x3fff80000001fffc0000000. After that, when hot-adding socket#2 and #3, each core of sockets is numbered as follows: | CPU# Socket#0 | 0-14 , 60-74 Socket#1 | 15-29, 75-89 Socket#2 | 30-59 Socket#3 | 90-119 Then llc_shared_mask of CPU#30 becomes 0x3fff8000fffffffc0000000. It means that last level cache of Socket#2 is shared with CPU#30-59 and 90-104. So the mask has the wrong value.

Most atomic operations were followed by one and none were preceded by smp_mb__before_atomic(), nor accompanied by a comment explaining the need for a barrier. Instead of trying to prove for every case whether or not it is needed, this patch introduces atomic_inc_mb() and atomic_dec_mb(), which explicitly include the memory barriers before and after the atomic operation. For now they are defined in a target header, although they could be of general use. Most of the existing atomic/mb combinations were replaced by the new helpers. In a few cases the atomic was sandwiched in spin_lock/spin_unlock and I simply removed the barrier. I suspect that in most cases the correct conversion would have been to drop the barrier. I also suspect that a few cases exist where a) the barrier was necessary and b) a second barrier before the atomic would have been necessary and got added by this patch.

If a socket gets a zero window ACK when it is transmitting data, the RTO is used to probe the window. The socket is aborted after roughly tcp_orphan_retries() retries (as in tcp_write_timeout()). But if the socket was idle when it received the zero window ACK, and later wants to send more data, we use the probe timer to probe the window. If the receiver always returns zero window ACKs, icsk_probes keeps getting reset in tcp_ack() and the orphan socket can stall forever until the system reaches the orphan limit (as commented in tcp_probe_timer()). This opens up a simple attack to create lots of hanging orphan sockets to burn the memory and the CPU, as demonstrated in the recent netdev post "TCP connection will hang in FIN_WAIT1 after closing if zero window is advertised." http://www.spinics.net/lists/netdev/msg296539.html This patch follows the design in RTO-based probe: we abort an orphan socket stalling on zero window when the probe timer reaches both the maximum backoff and the maximum RTO. For example, an 100ms RTT connection will timeout after roughly 153 seconds (0.3 + 0.6 + .... + 76.8) if the receiver keeps the window shut. If the orphan socket passes this check, but the system already has too many orphans (as in tcp_out_of_resources()), we still abort it but we'll also send an RST packet as the connection may still be active. In addition, we change TCP_USER_TIMEOUT to cover (life or dead) sockets stalled on zero-window probes. This changes the semantics of TCP_USER_TIMEOUT slightly because it previously only applies when the socket has pending transmission.

In theory the sorting should be performed by the underlying disk scheduler, however, in practice the disk scheduler only accepts and sorts a finite number of requests. To allow the sorting of all requests, dm-crypt needs to implement its own own sorting. The overhead associated with rbtree-based sorting is considered negligible so it is not used conditionally. Even on SSD sorting can be beneficial since in-order request dispatch promotes lower latency IO completion to the upper layers.

On a multiprocessor machine, encryption requests finish in a different order than they were submitted. Consequently, write requests would be submitted in a different order and it could cause severe performance degradation. Move the submission of write requests to a separate thread so that the requests can be sorted before submitting. But this commit improves dm-crypt performance even without having dm-crypt perform request sorting (in particular it enables IO schedulers like CFQ to sort more effectively). Note: it is required that a previous commit ("dm crypt: don't allocate pages for a partial request") be applied before applying this patch. Otherwise, this commit could introduce a crash.

The function crypt_alloc_buffer may be called concurrently. If we allocate from the mempool concurrently, there is a possibility of deadlock. For example, if we have mempool of 256 pages, two processes, each wanting 256, pages allocate from the mempool concurrently, it may deadlock in a situation where both processes have allocated 128 pages and the mempool is exhausted. In order to avoid such a scenario, we allocate the pages under a mutex. In order to not degrade performance with excessive locking, we try non-blocking allocations without a mutex first and if it fails, we fallback to a blocking allocation with a mutex.

Since we already have the struct irq_data, call __get_cached_msi_msg() directly and skip the lookup work done by get_cached_msi_msg(). No functional change.

Previously, the sysfs file existed for endpoints but did nothing. Add "msi_bus" support for endpoints, so an administrator can prevent the use of MSI and MSI-X for individual devices. Note that as for bridges, these changes only affect future driver requests for MSI or MSI-X, so drivers may need to be reloaded. Add documentation for the "msi_bus" sysfs file.

The problem had to do with the rename function: The function found space for the new dirent, and remembered that location. But then the old dirent was removed, which often moved the eligible location for the renamed dirent. Putting the new dirent at the saved location caused file system corruption. This patch adds a new "save_loc" variable to struct gfs2_diradd. If 1, the dirent location is saved. If 0, the dirent location is not saved and the buffer_head is released as per previous behavior.

Main idea is to define multiple UFS low power levels based on UFS device and UFS link power states. This would allow any specific platform or pci driver to choose the best suited low power level during runtime and system suspend based on their power goals. bkops handlig: To put the UFS device in sleep state when bkops is disabled, first query the bkops status from the device and enable bkops on device only if device needs time to perform the bkops. START_STOP handling: Before sending START_STOP_UNIT to the device well-known logical unit (w-lun) to make sure that the device w-lun unit attention condition is cleared. Write protection: UFS device specification allows LUs to be write protected, either permanently or power on write protected. If any LU is power on write protected and if the card is power cycled (by powering off VCCQ and/or VCC rails), LU's write protect status would be lost. So this means those LUs can be written now. To ensures that UFS device is power cycled only if the power on protect is not set for any of the LUs, check if power on write protect is set and if device is in sleep/power-off state & link in inactive state (Hibern8 or OFF state). If none of the Logical Units on UFS device is power on write protected then all UFS device power rails (VCC, VCCQ & VCCQ2) can be turned off if UFS device is in power-off state and UFS link is in OFF state. But current implementation would disable all device power rails even if UFS link is not in OFF state. Low power mode: If UFS link is in OFF state then UFS host controller can be power collapsed to avoid leakage current from it. Note that if UFS host controller is power collapsed, full UFS reinitialization will be required on resume to re-establish the link between host and device.

LUN number reported from UFS device could be 0xC17F hence this patch advertise the "max_lun" as 0xC17F which will allow SCSI mid layer to detect the W-LUs as well. But once the W-LUs are detected, UFSHCD driver may get the commands with SCSI LUN id upto 0xC17F but UPIU LUN id field is only 8-bit wide so it requires the mapping of SCSI LUN id to UPIU LUN id. This patch also add support for this mapping.

commit e396900 upstream. Add a drm_sysfs_connector_remove call when we destroy the panel to make sure the connector node in sysfs gets deleted. This is required for proper unload and re-load of this driver as a module.

When I used netdev_for_each_lower_dev in commit bad5316 ("vrf: remove slave queue and private slave struct") I thought that it acts like netdev_for_each_lower_private and can be used to remove the current device from the list while walking, but unfortunately it acts more like netdev_for_each_lower_private_rcu and doesn't allow it. The difference is where the "iter" points to, right now it points to the current element and that makes it impossible to remove it. Change the logic to be similar to netdev_for_each_lower_private and make it point to the "next" element so we can safely delete the current one. VRF is the only such user right now, there's no change for the read-only users.

Instead, we could just save pointers to these actions in tcf_exts, since they are refcount'ed, so convert the list to an array of pointers. The "ugly" part is the action API still accepts list as a parameter, I just introduce a helper function to convert the array of pointers to a list, instead of relying on the C99 feature to iterate the array.

Fix that by marking ports as inactive only after unregistering them.

To fix this, the patch changes the logic when determining the total number of TCs enabled. Before, this would use the highest TC number enabled and assume that all TCs below it were also enabled. Now, we create a bitmask of enabled TCs and scan it to determine not only the number of TCs, but also if the set of enabled TCs starts at zero and is contiguous. If not, then DCB is disabled by only returning one TC.

Add PHY delay compensation in igb_ptp_rx_pktstamp(). In the IGB driver, there are two functions that retrieve timestamps received by the PHY - igb_ptp_rx_rgtstamp() and igb_ptp_rx_pktstamp(). The previous commit only changed igb_ptp_rx_rgtstamp(), and the change was incorrect. There are two instances in which PHY delay compensations should be made: - Before the packet transmission over the PHY, the latency between when the packet is timestamped and transmission of the packets, should be an add operation, but it is currently a subtract. - After the packets are received from the PHY, the latency between the receiving and timestamping of the packets should be a subtract operation, but it is currently an add.

As it is being executed from netdev notifier chain we hold rtnl lock when we get here. - we enter while (atomic_read(&net_device_ctx->vf_use_cnt) != 0) loop and wait till netvsc_notify_peers() drops vf_use_cnt. - netvsc_notify_peers() starts on some other CPU but netdev_notify_peers() will hang on rtnl_lock(). - deadlock! Instead of introducing additional synchronization I suggest we drop gwrk.dwrk completely and call NETDEV_NOTIFY_PEERS directly. As we're acting under rtnl lock this is legitimate.

IOW, consider size needed by a single spinlock when determining number of locks per cpu. So with 64 byte per cacheline and 4 byte per spinlock this gives 32 locks per cpu.

This prevented the false positive lockdep warning on configurations such as: eth0 <--- macvlan0 <--- vlan0 <--- macvlan1 However, this doesn't prevent a warning on a configuration such as: eth0 <--- macvlan0 <--- vlan0 eth1 <--- vlan1 <--- macvlan1 In this case, all the locks end up with a nesting subclass of 1, so lockdep thinks that there is still a deadlock: - in the first case we have (macvlan_netdev_addr_lock_key, 1) and then take (vlan_netdev_xmit_lock_key, 1) - in the second case, we have (vlan_netdev_xmit_lock_key, 1) and then take (macvlan_netdev_addr_lock_key, 1) By removing the linktype check in dev_get_nest_level() and always incrementing the nesting depth, lockdep considers this configuration valid.

There are multiple issues at once. First, using skb_store_bits() is not correct since even if we have a cloned skb, page frags can still be shared. To really make them private, we need to pull them in via __pskb_pull_tail() first, which also gets us a private head via pskb_expand_head() implicitly. This is for helpers like bpf_skb_store_bytes(), bpf_l3_csum_replace(), bpf_l4_csum_replace(). Really, the only thing reasonable and working here is to call skb_ensure_writable() before any write operation. Meaning, via pskb_may_pull() it makes sure that parts we want to access are pulled in and if not does so plus unclones the skb implicitly. If our write_len still fits the headlen and we're cloned and our header of the clone is not writable, then we need to make a private copy via pskb_expand_head(). skb_store_bits() is a bit misleading and only safe to store into non-linear data in different contexts such as 357b40a18b04 ("[IPV6]: IPV6_CHECKSUM socket option can corrupt kernel memory"). For above BPF helper functions, it means after fixed bpf_try_make_writable(), we've pulled in enough, so that we operate always based on skb->data. Thus, the call to skb_header_pointer() and skb_store_bits() becomes superfluous. In bpf_skb_store_bytes(), the len check is unnecessary too since it can only pass in maximum of BPF stack size, so adding offset is guaranteed to never overflow. Also bpf_l3/4_csum_replace() helpers must test for proper offset alignment since they use __sum16 pointer for writing resulting csum. The remaining helpers that change skb data not discussed here yet are bpf_skb_vlan_push(), bpf_skb_vlan_pop() and bpf_skb_change_proto(). The vlan helpers internally call either skb_ensure_writable() (pop case) and skb_cow_head() (push case, for head expansion), respectively. Similarly, bpf_skb_proto_xlat() takes care to not mangle page frags.

Tejun says: So, I think in_cgroup should mean that the object is in that particular cgroup while under_cgroup in the subhierarchy of that cgroup. Let's rename the other subhierarchy test to under too. I think that'd be a lot less confusing going forward. [...] It's more intuitive and gives us the room to implement the real "in" test if ever necessary in the future. Since this touches uapi bits, we need to change this as long as v4.8 is not yet officially released. Thus, change the helper enum and rename related bits.

With this patch, the 'bpftool link' runs successfully with 'pids'. $ tools/build/bpftool/bpftool link ... 4: tracing prog 23 prog_type lsm attach_type lsm_mac target_obj_id 1 target_btf_id 31320 pids systemd(1) Fixes: 44ba7b3 ("bpftool: Use a local copy of BPF_LINK_TYPE_PERF_EVENT in pid_iter.bpf.c") Signed-off-by: Yonghong Song <yonghong.song@linux.dev> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Tested-by: Quentin Monnet <quentin@isovalent.com> Reviewed-by: Quentin Monnet <quentin@isovalent.com> Link: https://lore.kernel.org/bpf/20240312023249.3776718-1-yonghong.song@linux.dev Signed-off-by: Sasha Levin <sashal@kernel.org>

pmd_leaf()/pud_leaf() only implies a pmd_present()/pud_present() check on some architectures. We really should check for pmd_present()/pud_present() first. This should explain the report we got on ppc64 (which has CONFIG_PGTABLE_HAS_HUGE_LEAVES set in the config) that triggered: VM_WARN_ON_ONCE(pmd_leaf(pmdp_get_lockless(pmdp))); Likely we had a PMD migration entry for which pmd_leaf() did not trigger. We raced with restoring the PMD migration entry, and suddenly saw a pmd_leaf(). In this case, pte_offset_map_lock() saved us from more trouble, because it rechecks the PMD value, but we would not have processed the migration entry -- which is not too bad because the only user of FW_MIGRATION is KSM for unsharing, and KSM only applies to small folios. Further, we shouldn't re-read the PMD/PUD value for our warning, the primary purpose of the VM_WARN_ON_ONCE() is to find spurious use of pmd_leaf()/pud_leaf() without CONFIG_PGTABLE_HAS_HUGE_LEAVES. As a side note, we are currently not implementing FW_MIGRATION support for PUD migration entries, which likely should exist due to hugetlb. Add a TODO so this won't fall through the cracks if more FW_MIGRATION users get added. Was able to write a quick reproducer and verify that the issue no longer triggers with this fix. https://gitlab.com/davidhildenbrand/scratchspace/-/blob/main/reproducers/move-pages-pmd-leaf.c Without this fix after a couple of seconds in a VM with 2 NUMA nodes: [ 54.333753] ------------[ cut here ]------------ [ 54.334901] WARNING: CPU: 20 PID: 1704 at mm/pagewalk.c:815 folio_walk_start+0x48f/0x6e0 [ 54.336455] Modules linked in: ...
