The symlink readpage isn't given a file pointer, so the handling has to be special-cased. This has been posted as part of a patchset to foliate netfs, afs, etc.[1] but I've moved it to this one as it's not actually doing foliation but is more of a pre-cleanup. - Fix file creation to set the mtime from the client's clock to keep make happy if the server's clock isn't quite in sync.[2] Link: https://lore.kernel.org/r/163005742570.2472992.7800423440314043178.stgit@warthog.procyon.org.uk/ [1] Link: http://lists.infradead.org/pipermail/linux-afs/2021-October/004395.html [2] * tag 'afs-next-20211102' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: afs: Set mtime from the client for yfs create operations afs: Sort out symlink reading |

Changes in gfs2:
* Fix a locking order inversion between the inode and iopen glocks in gfs2_inode_lookup. * Implement proper queuing of glock holders for glocks that require instantiation (like reading an inode or bitmap blocks from disk). Before, multiple glock holders could race with each other and half-initialized objects could be exposed; the GL_SKIP flag further exacerbated this problem. * Fix a rare deadlock between inode lookup / creation and remote delete work. * Fix a rare scheduling-while-atomic bug in dlm during glock hash table walks. * Various other minor fixes and cleanups. -----BEGIN PGP SIGNATURE----- iQJIBAABCAAyFiEEJZs3krPW0xkhLMTc1b+f6wMTZToFAmGBThoUHGFncnVlbmJh QHJlZGhhdC5jb20ACgkQ1b+f6wMTZTp4vg/9HQbZYtl1R7qWlzaEAOHaZzudcRIS wnCGGxqdySdWogXhBCICwyH7nJneFG1XsYvNF8HmH10ALjZkjWM3MV0J9O00eCWk VXKqcioRbWtyQiye3A3icT6qhVGd65LK+p6GqtH7pQXOYc1ein/Gi/IWHFN6wCTM FXulFAo6i3Uep4lfz9+WPy8iGDVVLUWt0uhmY8O+W8edsDJdX7Kr89mQU/2dUsMp BxImDvKcchd8SlWOHNJ2WrbfPVFLd3mgmouojxn7/0pspqtJA6tgOWpAmN0uKw+V Qaqb9g0KjrAnH39w1wSzlN9XCItOvT3EGg1HEkl1kx5UDi4S/B9yF0wWbzfI2BUL 9T0dyAbmIcamcHua+rQatTfBQnEOScNfZQKd9MHE4etLhVyE2fHjmx2Ya4xcmiy/ /onUEcfjcQvzVY+69hD9cqKwwgTz5G2xyLzD7WdWJD10qU4z22arOSIedmC2c1Eq 62cbaxcHXrDkG8FYHb/ukNeZ8Fw54niWnBCXDBfRxpx/UbJDzvNxjF2BPNJEBWON UFO8cbMVMojrsLkkWKTInecCLjhROwgWXUo8A1CmYQNlMUhObWts2jGoRlUYBUcH 8Ah+DADcz9H8VV2koURo6ZkJyJBztgJOZ+ysFZSdPQ2HQnijwWqi8Zn33UfTZH6d BxxPK+wVfPNZSWQ= =sAlR -----END PGP SIGNATURE----- Merge tag 'gfs2-v5.15-rc5-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2 Pull gfs2 updates from Andreas Gruenbacher: - Fix a locking order inversion between the inode and iopen glocks in gfs2_inode_lookup. - Implement proper queuing of glock holders for glocks that require instantiation (like reading an inode or bitmap blocks from disk).

gfs2: Fix mmap + page fault deadlocks
Functions gfs2_file_read_iter and gfs2_file_write_iter are both
accessing the user buffer to write to or read from while holding the
inode glock. In the most basic scenario, that buffer will not be
resident and it will be mapped to the same file. Accessing the buffer
will trigger a page fault, and gfs2 will deadlock trying to take the
same inode glock again while trying to handle that fault.
Fix that and similar, more complex scenarios by disabling page faults
while accessing user buffers. To make this work, introduce a small
amount of new infrastructure and fix some bugs that didn't trigger so
far, with page faults enabled.

afs: Set mtime from the client for yfs create operations
For operations that create vnodes on the server such as CreateFile, MakeDir or Symlink, the server will store its own current time as the mtime if the client doesn't pass in a time in the accompanying StoreStatus structure. If the server and client clocks are not well synchronized, the client may see timestamps in the future or inconsistent dependency checks with "make" for files that are not modified after creation: make[2]: Warning: File 'arch/x86/kernel/apic/modules.order' has modification time 0.14 s in the future make[2]: warning: Clock skew detected. Your build may be incomplete. This is already handled correctly for non yfs operations; also set the mtime for the corresponding yfs operations.

Pull selinux updates from Paul Moore:
- Add LSM/SELinux/Smack controls and auditing for io-uring.
As usual, the individual commit descriptions have more detail, but we
were basically missing two things which we're adding here:
+ establishment of a proper audit context so that auditing of
io-uring ops works similarly to how it does for syscalls (with
some io-uring additions because io-uring ops are *not* syscalls)
+ additional LSM hooks to enable access control points for some of
the more unusual io-uring features, e.g. credential overrides.
The additional audit callouts and LSM hooks were done in conjunction
with the io-uring folks, based on conversations and RFC patches
earlier in the year.
- Fixup the binder credential handling so that the proper credentials
are used in the LSM hooks; the commit description and the code
comment which is removed in these patches are helpful to understand
the background and why this is the proper fix.
- Enable SELinux genfscon policy support for securityfs, allowing
improved SELinux filesystem labeling for other subsystems which make
use of securityfs, e.g. IMA.

Tracing updates for 5.16:
- kprobes: Restructured stack unwinder to show properly on x86 when a stack dump happens from a kretprobe callback. - Fix to bootconfig parsing - Have tracefs allow owner and group permissions by default (only denying others). There's been pressure to allow non root to tracefs in a controlled fashion, and using groups is probably the safest. - Bootconfig memory managament updates. - Bootconfig clean up to have the tools directory be less dependent on changes in the kernel tree. - Allow perf to be traced by function tracer. - Rewrite of function graph tracer to be a callback from the function tracer instead of having its own trampoline (this change will happen on an arch by arch basis, and currently only x86_64 implements it). - Allow multiple direct trampolines (bpf hooks to functions) be batched together in one synchronization. - Allow histogram triggers to add variables that can perform calculations against the event's fields. - Use the linker to determine architecture callbacks from the ftrace trampoline to allow for proper parameter prototypes and prevent warnings from the compiler. - Extend histogram triggers to key off of variables. - Have trace recursion use bit magic to determine preempt context over if branches. - Have trace recursion disable preemption as all use cases do anyway. - Added testing for verification of tracing utilities. - Various small clean ups and fixes. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCYYBdxhQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qp1sAQD2oYFwaG3sx872gj/myBcHIBSKdiki Hry5csd8zYDBpgD+Poylopt5JIbeDuoYw/BedgEXmscZ8Qr7VzjAXdnv/Q4= =Loz8 -----END PGP SIGNATURE----- Merge tag 'trace-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: - kprobes: Restructured stack unwinder to show properly on x86 when a stack dump happens from a kretprobe callback. - Fix to bootconfig parsing - Have tracefs allow owner and group permissions by default (only denying others).

net: ndisc: introduce ndisc_evict_nocarrier sysctl parameter
In most situations the neighbor discovery cache should be cleared on a NOCARRIER event which is currently done unconditionally. But for wireless roams the neighbor discovery cache can and should remain intact since the underlying network has not changed. This patch introduces a sysctl option ndisc_evict_nocarrier which can be disabled by a wireless supplicant during a roam. This allows packets to be sent after a roam immediately without having to wait for neighbor discovery. A user reported roughly a 1 second delay after a roam before packets could be sent out (note, on IPv4). This delay was due to the ARP cache being cleared. During testing of this same scenario using IPv6 no delay was noticed, but regardless there is no reason to clear the ndisc cache for wireless roams.

libbpf: Deprecate AF_XDP support
Deprecate AF_XDP support in libbpf ([0]). This has been moved to libxdp as it is a better fit for that library. The AF_XDP support only uses the public libbpf functions and can therefore just use libbpf as a library from libxdp. The libxdp APIs are exactly the same so it should just be linking with libxdp instead of libbpf for the AF_XDP functionality. If not, please submit a bug report. Linking with both libraries is supported but make sure you link in the correct order so that the new functions in libxdp are used instead of the deprecated ones in libbpf. Libxdp can be found at https://github.com/xdp-project/xdp-tools.

bpf: Fix propagation of signed bounds from 64-bit min/max into 32-bit.
Similar to unsigned bounds propagation fix signed bounds.
The 'Fixes' tag is a hint. There is no security bug here.
The verifier was too conservative.

bpf: Fix propagation of bounds from 64-bit min/max into 32-bit and var_off.
Before this fix: 166: (b5) if r2 <= 0x1 goto pc+22 from 166 to 189: R2=invP(id=1,umax_value=1,var_off=(0x0; 0xffffffff)) After this fix: 166: (b5) if r2 <= 0x1 goto pc+22 from 166 to 189: R2=invP(id=1,umax_value=1,var_off=(0x0; 0x1)) While processing BPF_JLE the reg_set_min_max() would set true_reg->umax_value = 1 and call __reg_combine_64_into_32(true_reg). Without the fix it would not pass the condition: if (__reg64_bound_u32(reg->umin_value) && __reg64_bound_u32(reg->umax_value)) since umin_value == 0 at this point. Before commit |

overflow updates for v5.16-rc1
The end goal of the current buffer overflow detection work[0] is to gain full compile-time and run-time coverage of all detectable buffer overflows seen via array indexing or memcpy(), memmove(), and memset(). The str*() family of functions already have full coverage. While much of the work for these changes have been on-going for many releases (i.e. 0-element and 1-element array replacements, as well as avoiding false positives and fixing discovered overflows[1]), this series contains the foundational elements of several related buffer overflow detection improvements by providing new common helpers and FORTIFY_SOURCE changes needed to gain the introspection required for compiler visibility into array sizes. Also included are a handful of already Acked instances using the helpers (or related clean-ups), with many more waiting at the ready to be taken via subsystem-specific trees[2]. The new helpers are: - struct_group() for gaining struct member range introspection. - memset_after() and memset_startat() for clearing to the end of structures. - DECLARE_FLEX_ARRAY() for using flex arrays in unions or alone in structs. Also included is the beginning of the refactoring of FORTIFY_SOURCE to support memcpy() introspection, fix missing and regressed coverage under GCC, and to prepare to fix the currently broken Clang support. Finishing this work is part of the larger series[0], but depends on all the false positives and buffer overflow bug fixes to have landed already and those that depend on this series to land. As part of the FORTIFY_SOURCE refactoring, a set of both a compile-time and run-time tests are added for FORTIFY_SOURCE and the mem*()-family functions respectively. The compile time tests have found a legitimate (though corner-case) bug[6] already. Please note that the appearance of "panic" and "BUG" in the FORTIFY_SOURCE refactoring are the result of relocating existing code, and no new use of those code-paths are expected nor desired. Finally, there are two tree-wide conversions for 0-element arrays and flexible array unions to gain sane compiler introspection coverage that result in no known object code differences. After this series (and the changes that have now landed via netdev and usb), we are very close to finally being able to build with -Warray-bounds and -Wzero-length-bounds. However, due corner cases in GCC[3] and Clang[4], I have not included the last two patches that turn on these options, as I don't want to introduce any known warnings to the build. Hopefully these can be solved soon.

cpu-to-thread_info update for v5.16-rc1
Cross-architecture update to move task_struct::cpu back into thread_info
on arm64, x86, s390, powerpc, and riscv. All Acked by arch maintainers.
Quoting Ard Biesheuvel:
"Move task_struct::cpu back into thread_info
Keeping CPU in task_struct is problematic for architectures that define
raw_smp_processor_id() in terms of this field, as it requires
linux/sched.h to be included, which causes a lot of pain in terms of
circular dependencies (aka 'header soup')
This series moves it back into thread_info (where it came from) for all
architectures that enable THREAD_INFO_IN_TASK, addressing the header
soup issue as well as some pointless differences in the implementations
of task_cpu() and set_task_cpu()."
