AF_RXRPC is incorrectly sending back to the server any abort it receives for a client connection. This is due to the final-ACK offload to the connection event processor patch. The abort code is copied into the last-call information on the connection channel and then the event processor is set. Instead, the following should be done: (1) In the case of a final-ACK for a successful call, the ACK should be scheduled as before. (2) In the case of a locally generated ABORT, the ABORT details should be cached for sending in response to further packets related to that call and no further action scheduled at call disconnect time. (3) In the case of an ACK received from the peer, the call should be considered dead, no ABORT should be transmitted at this time. In response to further non-ABORT packets from the peer relating to this call, an RX_USER_ABORT ABORT should be transmitted. (4) In the case of a call killed due to network error, an RX_USER_ABORT ABORT should be cached for transmission in response to further packets, but no ABORT should be sent at this time.

Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for you net tree, they are: 1) Restore __GFP_NORETRY in xt_table allocations to mitigate effects of large memory allocation requests, from Michal Hocko. 2) Release IPv6 fragment queue in case of error in fragmentation header, this is a follow up to amend patch 83f1999c, from Subash Abhinov Kasiviswanathan. 3) Flowtable infrastructure depends on NETFILTER_INGRESS as it registers a hook for each flowtable, reported by John Crispin. 4) Missing initialization of info->priv in xt_cgroup version 1, from Cong Wang. 5) Give a chance to garbage collector to run after scheduling flowtable cleanup. 6) Releasing flowtable content on nft_flow_offload module removal is not required at all, there is not dependencies between this module and flowtables, remove it. 7) Fix missing xt_rateest_mutex grabbing for hash insertions, also from Cong Wang. 8) Move nf_flow_table_cleanup() routine to flowtable core, this patch is a dependency for the next patch in this list. 9) Flowtable resources are not properly released on removal from the control plane. Fix this resource leak by scheduling removal of all entries and explicit call to the garbage collector. 10) nf_ct_nat_offset() declaration is dead code, this function prototype is not used anywhere, remove it. From Taehee Yoo. 11) Fix another flowtable resource leak on entry insertion failures, this patch also fixes a possible use-after-free. Patch from Felix Fietkau. ==================== Signed-off-by:

flow_offload_del frees the flow, so all associated resource must be freed before. Since the ct entry in struct flow_offload_entry was allocated by flow_offload_alloc, it should be freed by flow_offload_free to take care of the error handling path when flow_offload_add fails. While at it, make flow_offload_del static, since it should never be called directly, only from the gc step Signed-off-by:

The pipe buffer limits are accessed without any locking, and may be changed at any time by the sysctl handlers. In theory this could cause problems for expressions like the following: pipe_user_pages_hard && user_bufs > pipe_user_pages_hard ... since the assembly code might reference the 'pipe_user_pages_hard' memory location multiple times, and if the admin removes the limit by setting it to 0, there is a very brief window where processes could incorrectly observe the limit to be exceeded. Fix this by loading the limits with READ_ONCE() prior to use. Link: http://lkml.kernel.org/r/20180111052902.14409-8-ebiggers3@gmail.comSigned-off-by:Eric Biggers <ebiggers@google.com> Acked-by:

round_pipe_size() calculates the number of pages the requested size corresponds to, then rounds the page count up to the next power of 2. However, it also rounds everything < PAGE_SIZE up to PAGE_SIZE. Therefore, there's no need to actually translate the size into a page count; we just need to round the size up to the next power of 2. We do need to verify the size isn't greater than (1 << 31), since on 32-bit systems roundup_pow_of_two() would be undefined in that case. But that can just be combined with the UINT_MAX check which we need anyway now. Finally, update pipe_set_size() to not redundantly check the return value of round_pipe_size() for the "invalid size" case twice.

A pipe's size is represented as an 'unsigned int'. As expected, writing a value greater than UINT_MAX to /proc/sys/fs/pipe-max-size fails with EINVAL. However, the F_SETPIPE_SZ fcntl silently truncates such values to 32 bits, rather than failing with EINVAL as expected. (It *does* fail with EINVAL for values above (1 << 31) but <= UINT_MAX.) Fix this by moving the check against UINT_MAX into round_pipe_size() which is called in both cases. Link: http://lkml.kernel.org/r/20180111052902.14409-6-ebiggers3@gmail.comSigned-off-by:

pipe-user-pages-hard and pipe-user-pages-soft are only supposed to apply to unprivileged users, as documented in both Documentation/sysctl/fs.txt and the pipe(7) man page. However, the capabilities are actually only checked when increasing a pipe's size using F_SETPIPE_SZ, not when creating a new pipe. Therefore, if pipe-user-pages-hard has been set, the root user can run into it and be unable to create pipes. Similarly, if pipe-user-pages-soft has been set, the root user can run into it and have their pipes limited to 1 page each. Fix this by allowing the privileged override in both cases.

pipe_proc_fn() is no longer needed, as it only calls through to proc_dopipe_max_size(). Just put proc_dopipe_max_size() in the ctl_table entry directly, and remove the unneeded EXPORT_SYMBOL() and the ENOSYS stub for it. (The reason the ENOSYS stub isn't needed is that the pipe-max-size ctl_table entry is located directly in 'kern_table' rather than being registered separately. Therefore, the entry is already only defined when the kernel is built with sysctl support.) Link: http://lkml.kernel.org/r/20180111052902.14409-3-ebiggers3@gmail.comSigned-off-by:

Patch series "pipe: buffer limits fixes and cleanups", v2. This series simplifies the sysctl handler for pipe-max-size and fixes another set of bugs related to the pipe buffer limits: - The root user wasn't allowed to exceed the limits when creating new pipes. - There was an off-by-one error when checking the limits, so a limit of N was actually treated as N - 1. - F_SETPIPE_SZ accepted values over UINT_MAX. - Reading the pipe buffer limits could be racy. This patch (of 7): Before validating the given value against pipe_min_size, do_proc_dopipe_max_size_conv() calls round_pipe_size(), which rounds the value up to pipe_min_size. Therefore, the second check against pipe_min_size is redundant. Remove it. Link: http://lkml.kernel.org/r/20180111052902.14409-2-ebiggers3@gmail.comSigned-off-by:

We get a lot of very large stack frames using gcc-7.0.1 with the default -fsanitize-address-use-after-scope --param asan-stack=1 options, which can easily cause an overflow of the kernel stack, e.g. drivers/gpu/drm/i915/gvt/handlers.c:2434:1: warning: the frame size of 46176 bytes is larger than 3072 bytes drivers/net/wireless/ralink/rt2x00/rt2800lib.c:5650:1: warning: the frame size of 23632 bytes is larger than 3072 bytes lib/atomic64_test.c:250:1: warning: the frame size of 11200 bytes is larger than 3072 bytes drivers/gpu/drm/i915/gvt/handlers.c:2621:1: warning: the frame size of 9208 bytes is larger than 3072 bytes drivers/media/dvb-frontends/stv090x.c:3431:1: warning: the frame size of 6816 bytes is larger than 3072 bytes fs/fscache/stats.c:287:1: warning: the frame size of 6536 bytes is larger than 3072 bytes To reduce this risk, -fsanitize-address-use-after-scope is now split out into a separate CONFIG_KASAN_EXTRA Kconfig option, leading to stack frames that are smaller than 2 kilobytes most of the time on x86_64. An earlier version of this patch also prevented combining KASAN_EXTRA with KASAN_INLINE, but that is no longer necessary with gcc-7.0.1. All patches to get the frame size below 2048 bytes with CONFIG_KASAN=y and CONFIG_KASAN_EXTRA=n have been merged by maintainers now, so we can bring back that default now. KASAN_EXTRA=y still causes lots of warnings but now defaults to !COMPILE_TEST to disable it in allmodconfig, and it remains disabled in all other defconfigs since it is a new option. I arbitrarily raise the warning limit for KASAN_EXTRA to 3072 to reduce the noise, but an allmodconfig kernel still has around 50 warnings on gcc-7. I experimented a bit more with smaller stack frames and have another follow-up series that reduces the warning limit for 64-bit architectures to 1280 bytes (without CONFIG_KASAN). With earlier versions of this patch series, I also had patches to address the warnings we get with KASAN and/or KASAN_EXTRA, using a "noinline_if_stackbloat" annotation. That annotation now got replaced with a gcc-8 bugfix (see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81715) and a workaround for older compilers, which means that KASAN_EXTRA is now just as bad as before and will lead to an instant stack overflow in a few extreme cases. This reverts parts of commit 3f181b4d ("lib/Kconfig.debug: disable -Wframe-larger-than warnings with KASAN=y"). Two patches in linux-next should be merged first to avoid introducing warnings in an allmodconfig build: 3cd890db ("media: dvb-frontends: fix i2c access helpers for KASAN") 16c3ada8 ("media: r820t: fix r820t_write_reg for KASAN") Do we really need to backport this? I think we do: without this patch, enabling KASAN will lead to unavoidable kernel stack overflow in certain device drivers when built with gcc-7 or higher on linux-4.10+ or any version that contains a backport of commit c5caf21a. Most people are probably still on older compilers, but it will get worse over time as they upgrade their distros. The warnings we get on kernels older than this should all be for code that uses dangerously large stack frames, though most of them do not cause an actual stack overflow by themselves.The asan-stack option was added in linux-4.0, and commit 3f181b4d ("lib/Kconfig.debug: disable -Wframe-larger-than warnings with KASAN=y") effectively turned off the warning for allmodconfig kernels, so I would like to see this fix backported to any kernels later than 4.0. I have done dozens of fixes for individual functions with stack frames larger than 2048 bytes with asan-stack, and I plan to make sure that all those fixes make it into the stable kernels as well (most are already there). Part of the complication here is that asan-stack (from 4.0) was originally assumed to always require much larger stacks, but that turned out to be a combination of multiple gcc bugs that we have now worked around and fixed, but sanitize-address-use-after-scope (from v4.10) has a much higher inherent stack usage and also suffers from at least three other problems that we have analyzed but not yet fixed upstream, each of them makes the stack usage more severe than it should be.

After these patches there is no sleeping operation in clear_inode(). So, remove might_sleep() from it. Link: http://lkml.kernel.org/r/20171108004354.40308-1-shakeelb@google.comSigned-off-by:
