When registering the IRQ handler fails, do not just return the error code, this will free the devm_kzalloc()-ed data struct while leaving the queued work queued and the registered power_supply registered with both of them now pointing to free-ed memory, resulting in various kernel crashes soon afterwards. Instead properly tear-down things on IRQ handler register errors. Fixes: 703df6c09795 ("power: bq27xxx_battery: Reorganize I2C into a module") Cc: Andrew F.

2021-11-02mips: cm: Convert to bitfield API to fix out-of-bounds accessGeert Uytterhoeven2-17/+16
mips_cm_error_report() extracts the cause and other cause from the error register using shifts. This works fine for the former, as it is stored in the top bits, and the shift will thus remove all non-related bits. However, the latter is stored in the bottom bits, hence thus needs masking to get rid of non-related bits. Without such masking, using it as an index into the cm2_causes[] array will lead to an out-of-bounds access, probably causing a crash. Fix this by using FIELD_GET() instead. Bite the bullet and convert all MIPS CM handling to the bitfield API, to improve readability and safety.

2021-11-02afs: Set mtime from the client for yfs create operationsMarc Dionne1-19/+13
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.

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. * tag 'selinux-pr-20211101' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: security: Return xattr name from security_dentry_init_security() selinux: fix a sock regression in selinux_ip_postroute_compat() binder: use cred instead of task for getsecid binder: use cred instead of task for selinux checks binder: use euid from cred instead of using task LSM: Avoid warnings about potentially unused hook variables selinux: fix all of the W=1 build warnings selinux: make better use of the nf_hook_state passed to the NF hooks selinux: fix race condition when computing ocontext SIDs selinux: remove unneeded ipv6 hook wrappers selinux: remove the SELinux lockdown implementation selinux: enable genfscon labeling for securityfs Smack: Brutalist io_uring support selinux: add support for the io_uring access controls lsm,io_uring: add LSM hooks to io_uring io_uring: convert io_uring to the secure anon inode interface fs: add anon_inode_getfile_secure() similar to anon_inode_getfd_secure() audit: add filtering for io_uring records audit,io_uring,io-wq: add some basic audit support to io_uring audit: prepare audit_context for use in calling contexts beyond syscalls

2021-11-01net: ndisc: introduce ndisc_evict_nocarrier sysctl parameterJames Prestwood5-1/+34
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.

2021-11-01net: arp: introduce arp_evict_nocarrier sysctl parameterJames Prestwood6-1/+27
This change introduces a new sysctl parameter, arp_evict_nocarrier. When set (default) the ARP cache will be cleared on a NOCARRIER event. This new option has been defaulted to '1' which maintains existing behavior. Clearing the ARP cache on NOCARRIER is relatively new, introduced by: commit 859bd2ef1fc1110a8031b967ee656c53a6260a76 Author: David Ahern <[email protected]> Date: Thu Oct 11 20:33:49 2018 -0700 net: Evict neighbor entries on carrier down The reason for this changes is to prevent the ARP cache from being cleared when a wireless device roams. Specifically for wireless roams the ARP cache should not be cleared because the underlying network has not changed. Clearing the ARP cache in this case can introduce significant delays sending out packets after a roam. A user reported such a situation here: https://lore.kernel.org/linux-wireless/CACsRnHWa47zpx3D1oDq9JYnZWniS8yBwW1h0WAVZ6vrbwL_S0w@mail.gmail.com/ After some investigation it was found that the kernel was holding onto packets until ARP finished which resulted in this 1 second delay. It was also found that the first ARP who-has was never responded to, which is actually what caues the delay. This change is more or less working around this behavior, but again, there is no reason to clear the cache on a roam anyways. As for the unanswered who-has, we know the packet made it OTA since it was seen while monitoring. Why it never received a response is unknown. In any case, since this is a problem on the AP side of things all that can be done is to work around it until it is solved. Some background on testing/reproducing the packet delay: Hardware: - 2 access points configured for Fast BSS Transition (Though I don't see why regular reassociation wouldn't have the same behavior) - Wireless station running IWD as supplicant - A device on network able to respond to pings (I used one of the APs) Procedure: - Connect to first AP - Ping once to establish an ARP entry - Start a tcpdump - Roam to second AP - Wait for operstate UP event, and note the timestamp - Start pinging Results: Below is the tcpdump after UP. It was recorded the interface went UP at 10:42:01.432875. 10:42:01.461871 ARP, Request who-has 192.168.254.1 tell 192.168.254.71, length 28 10:42:02.497976 ARP, Request who-has 192.168.254.1 tell 192.168.254.71, length 28 10:42:02.507162 ARP, Reply 192.168.254.1 is-at ac:86:74:55:b0:20, length 46 10:42:02.507185 IP 192.168.254.71 > 192.168.254.1: ICMP echo request, id 52792, seq 1, length 64 10:42:02.507205 IP 192.168.254.71 > 192.168.254.1: ICMP echo request, id 52792, seq 2, length 64 10:42:02.507212 IP 192.168.254.71 > 192.168.254.1: ICMP echo request, id 52792, seq 3, length 64 10:42:02.507219 IP 192.168.254.71 > 192.168.254.1: ICMP echo request, id 52792, seq 4, length 64 10:42:02.507225 IP 192.168.254.71 > 192.168.254.1: ICMP echo request, id 52792, seq 5, length 64 10:42:02.507232 IP 192.168.254.71 > 192.168.254.1: ICMP echo request, id 52792, seq 6, length 64 10:42:02.515373 IP 192.168.254.1 > 192.168.254.71: ICMP echo reply, id 52792, seq 1, length 64 10:42:02.521399 IP 192.168.254.1 > 192.168.254.71: ICMP echo reply, id 52792, seq 2, length 64 10:42:02.521612 IP 192.168.254.1 > 192.168.254.71: ICMP echo reply, id 52792, seq 3, length 64 10:42:02.521941 IP 192.168.254.1 > 192.168.254.71: ICMP echo reply, id 52792, seq 4, length 64 10:42:02.522419 IP 192.168.254.1 > 192.168.254.71: ICMP echo reply, id 52792, seq 5, length 64 10:42:02.523085 IP 192.168.254.1 > 192.168.254.71: ICMP echo reply, id 52792, seq 6, length 64 You can see the first ARP who-has went out very quickly after UP, but was never responded to. Nearly a second later the kernel retries and gets a response. Only then do the ping packets go out. If an ARP entry is manually added prior to UP (after the cache is cleared) it is seen that the first ping is never responded to, so its not only an issue with ARP but with data packets in general. As mentioned prior, the wireless interface was also monitored to verify the ping/ARP packet made it OTA which was observed to be true.

2021-11-01of/fdt: Remove of_scan_flat_dt() usage for __fdt_scan_reserved_mem()Rob Herring1-28/+24
Use of the of_scan_flat_dt() function predates libfdt and is discouraged as libfdt provides a nicer set of APIs. Rework __fdt_scan_reserved_mem() to be called directly and use libfdt.

2021-11-01of: unittest: document intentional interrupt-map provider build warningFrank Rowand2-0/+25
A recently implemented dtc compiler warning reports a dts problem via a build warning: drivers/of/unittest-data/tests-interrupts.dtsi:32.26-35.6: Warning (interrupt_map): /testcase-data/interrupts/intmap1: Missing '#address-cells' in interrupt-map provider The warning will be addressed by a separate patch by suppressing the warning for .dts files that include this .dtsi. This patch documents why the warning is due to a deliberately incorrect .dtsi file so that no one will fix the .dtsi file to prevent the build warning.

2021-11-01of/unittest: Disable new dtc node_name_vs_property_name and interrupt_map ↵Rob Herring1-1/+7
warnings The unittest dtbs have various intentional errors which cause warnings. With the latest dtc sync to v1.6.1-19-g0a3a9d3449c8, we need to disable some new checks: node_name_vs_property_name and interrupt_map warnings. These warnings are also generated for static_base_1.dtb, so add DTC_FLAGS for it. Note that the interrupt_map warnings only appear once interrupt_provider warning is re-enabled globally. drivers/of/unittest-data/tests-interrupts.dtsi:32.26-35.6: Warning (interrupt_map): /testcase-data/interrupts/intmap1: Missing '#address-cells' in interrupt-map provider Fixes: c12632bfb611 ("scripts/dtc: Update to upstream version v1.6.1-19-g0a3a9d3449c8") Reported-by: Stephen Rothwell <[email protected]> Reviewed-by: Frank Rowand <[email protected]> Tested-by: Frank Rowand <[email protected]> Link: https://lore.kernel.org/r/[email protected]/ Signed-off-by: Rob Herring <[email protected]>
2021-11-01libbpf: Deprecate AF_XDP supportMagnus Karlsson1-38/+52
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.

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 10bf4e83167c the umin was incorrectly ingored. The commit 10bf4e83167c fixed the correctness issue, but pessimized propagation of 64-bit min max into 32-bit min max and corresponding var_off.
