2021-02-11ath10k: hold RCU lock when calling ieee80211_find_sta_by_ifaddr()Shuah Khan
ieee80211_find_sta_by_ifaddr() must be called under the RCU lock and the resulting pointer is only valid under RCU lock as well. Fix ath10k_wmi_tlv_op_pull_peer_stats_info() to hold RCU lock before it calls ieee80211_find_sta_by_ifaddr() and release it when the resulting pointer is no longer needed. This problem was found while reviewing code to debug RCU warn from ath10k_wmi_tlv_parse_peer_stats_info().

2021-02-12kbuild: fix CONFIG_TRIM_UNUSED_KSYMS build for ppc64Masahiro Yamada
Stephen Rothwell reported a build error on ppc64 when CONFIG_TRIM_UNUSED_KSYMS is enabled. Jessica Yu pointed out the cause of the error with the reference to the ppc64 ELF ABI: "Symbol names with a dot (.) prefix are reserved for holding entry point addresses. The value of a symbol named ".FN", if it exists, is the entry point of the function "FN". As it turned out, CONFIG_TRIM_UNUSED_KSYMS has never worked for ppc64, but this issue has been unnoticed until recently because this option depends on !UNUSED_SYMBOLS hence is disabled by all{mod,yes}config. (Then, it was uncovered by another patch removing UNUSED_SYMBOLS.) Removing the dot prefix in scripts/gen_autoksyms.sh fixes the issue. Please note it must be done before 'sort -u' because modules have both ._mcount and _mcount undefined when CONFIG_FUNCTION_TRACER=y.

2021-02-11cifs: Set CIFS_MOUNT_USE_PREFIX_PATH flag on setting cifs_sb->prepath.Shyam Prasad N
While debugging another issue today, Steve and I noticed that if a subdir for a file share is already mounted on the client, any new mount of any other subdir (or the file share root) of the same share results in sharing the cifs superblock, which e.g. can result in incorrect device name. While setting prefix path for the root of a cifs_sb, CIFS_MOUNT_USE_PREFIX_PATH flag should also be set. Without it, prepath is not even considered in some places, and output of "mount" and various /proc/<>/*mount* related options can be missing part of the device name.

2021-02-11xfs: consider shutdown in bmapbt cursor delete assertBrian Foster
The assert in xfs_btree_del_cursor() checks that the bmapbt block allocation field has been handled correctly before the cursor is freed. This field is used for accurate calculation of indirect block reservation requirements (for delayed allocations), for example. generic/019 reproduces a scenario where this assert fails because the filesystem has shutdown while in the middle of a bmbt record insertion. This occurs after a bmbt block has been allocated via the cursor but before the higher level bmap function (i.e. xfs_bmap_add_extent_hole_real()) completes and resets the field. Update the assert to accommodate the transient state if the filesystem has shutdown. While here, clean up the indentation and comments in the function.

2021-02-11selftests/bpf: Convert test_xdp_redirect.sh to bashBjörn Töpel
The test_xdp_redirect.sh script uses a bash feature, '&>'. On systems, e.g. Debian, where '/bin/sh' is dash, this will not work as expected. Use bash in the shebang to get the expected behavior. Further, using 'set -e' means that the error of a command cannot be captured without the command being executed with '&&' or '||'.

Since sleepable programs are now executing under migrate_disable the per-cpu maps are safe to use. The map-in-map were ok to use in sleepable from the time sleepable progs were introduced. Note that non-preallocated maps are still not safe, since there is no rcu_read_lock yet in sleepable programs and dynamically allocated map elements are relying on rcu protection. The sleepable programs have rcu_read_lock_trace instead. That limitation will be addresses in the future.

2021-02-11locking/arch: Move qrwlock.h include after qspinlock.hWaiman Long
include/asm-generic/qrwlock.h was trying to get arch_spin_is_locked via asm-generic/qspinlock.h. However, this does not work because architectures might be using queued rwlocks but not queued spinlocks (csky), or because they might be defining their own queued_* macros before including asm/qspinlock.h. To fix this, ensure that asm/spinlock.h always includes qrwlock.h after defining arch_spin_is_locked (either directly for csky, or via asm/qspinlock.h for other architectures). The only inclusion elsewhere is in kernel/locking/qrwlock.c. That one is really unnecessary because the file is only compiled in SMP configurations (config QUEUED_RWLOCKS depends on SMP) and in that case linux/spinlock.h already includes asm/qrwlock.h if needed, via asm/spinlock.h.

2021-02-11staging: rtl8723bs: Replace one-element array with flexible-array member in ↵Gustavo A. R. Silva
struct ndis_80211_var_ie There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Refactor the code according to the use of a flexible-array member in struct ndis_80211_var_ie, instead of a one-element array. Also, this helps with the ongoing efforts to enable -Warray-bounds and fix the following warnings: CC [M] drivers/staging/rtl8723bs/core/rtw_wlan_util.o In file included from ./drivers/staging/rtl8723bs/include/drv_types.h:20, from drivers/staging/rtl8723bs/core/rtw_wlan_util.c:9: drivers/staging/rtl8723bs/core/rtw_wlan_util.c: In function ‘HT_caps_handler’: ./drivers/staging/rtl8723bs/include/basic_types.h:108:11: warning: array subscript 1 is above array bounds of ‘u8[1]’ {aka ‘unsigned char[1]’} [-Warray-bounds] 108 | (EF1BYTE(*((u8 *)(__pstart)))) | ^ ./drivers/staging/rtl8723bs/include/basic_types.h:42:8: note: in definition of macro ‘EF1BYTE’ 42 | ((u8)(_val)) | ^~~~ ./drivers/staging/rtl8723bs/include/basic_types.h:127:4: note: in expansion of macro ‘LE_P1BYTE_TO_HOST_1BYTE’ 127 | (LE_P1BYTE_TO_HOST_1BYTE(__pstart) >> (__bitoffset)) & \ | ^~~~~~~~~~~~~~~~~~~~~~~ ./drivers/staging/rtl8723bs/include/rtw_ht.h:97:55: note: in expansion of macro ‘LE_BITS_TO_1BYTE’ 97 | #define GET_HT_CAPABILITY_ELE_RX_STBC(_pEleStart) LE_BITS_TO_1BYTE((_pEleStart)+1, 0, 2) | ^~~~~~~~~~~~~~~~ drivers/staging/rtl8723bs/core/rtw_wlan_util.c:1104:58: note: in expansion of macro ‘GET_HT_CAPABILITY_ELE_RX_STBC’ 1104 | if (TEST_FLAG(phtpriv->stbc_cap, STBC_HT_ENABLE_TX) && GET_HT_CAPABILITY_ELE_RX_STBC(pIE->data)) { | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/staging/rtl8723bs/core/rtw_wlan_util.c:1051:75: warning: array subscript 2 is above array bounds of ‘u8[1]’ {aka ‘unsigned char[1]’} [-Warray-bounds] 1051 | if ((pmlmeinfo->HT_caps.u.HT_cap_element.AMPDU_para & 0x3) > (pIE->data[i] & 0x3)) | ~~~~~~~~~^~~ drivers/staging/rtl8723bs/core/rtw_wlan_util.c: In function ‘check_assoc_AP’: drivers/staging/rtl8723bs/core/rtw_wlan_util.c:1606:19: warning: array subscript 4 is above array bounds of ‘u8[1]’ {aka ‘unsigned char[1]’} [-Warray-bounds] 1606 | if (pIE->data[4] == 1) | ~~~~~~~~~^~~ drivers/staging/rtl8723bs/core/rtw_wlan_util.c:1609:20: warning: array subscript 5 is above array bounds of ‘u8[1]’ {aka ‘unsigned char[1]’} [-Warray-bounds] 1609 | if (pIE->data[5] & RT_HT_CAP_USE_92SE) | ~~~~~~~~~^~~ drivers/staging/rtl8723bs/core/rtw_wlan_util.c:1613:19: warning: array subscript 5 is above array bounds of ‘u8[1]’ {aka ‘unsigned char[1]’} [-Warray-bounds] 1613 | if (pIE->data[5] & RT_HT_CAP_USE_SOFTAP) | ~~~~~~~~~^~~ drivers/staging/rtl8723bs/core/rtw_wlan_util.c:1617:20: warning: array subscript 6 is above array bounds of ‘u8[1]’ {aka ‘unsigned char[1]’} [-Warray-bounds] 1617 | if (pIE->data[6] & RT_HT_CAP_USE_JAGUAR_BCUT) { | ~~~~~~~~~^~~ [1] https://en.wikipedia.org/wiki/Flexible_array_member [2] https://www.kernel.org/doc/html/v5.9/process/deprecated.html#zero-length-and-one-element-arrays Link: https://github.com/KSPP/linux/issues/79 Link: https://github.com/KSPP/linux/issues/109 Build-tested-by: kernel test robot <lkp@intel.com> Link: https://lore.kernel.org/lkml/602434b8.jc5DoXJ0bmHoxgIL%25lkp@intel.com/ Signed-off-by: Gustavo A.
