2021-05-04net: Only allow init netns to set default tcp cong to a restricted algoJonathon Reinhart1-0/+4
tcp_set_default_congestion_control() is netns-safe in that it writes to &net->ipv4.tcp_congestion_control, but it also sets ca->flags |= TCP_CONG_NON_RESTRICTED which is not namespaced. This has the unintended side-effect of changing the global net.ipv4.tcp_allowed_congestion_control sysctl, despite the fact that it is read-only: 97684f0970f6 ("net: Make tcp_allowed_congestion_control readonly in non-init netns") Resolve this netns "leak" by only allowing the init netns to set the default algorithm to one that is restricted. This restriction could be removed if tcp_allowed_congestion_control were namespace-ified in the future. This bug was uncovered with https://github.com/JonathonReinhart/linux-netns-sysctl-verify Fixes: 6670e1524477 ("tcp: Namespace-ify sysctl_tcp_default_congestion_control") Signed-off-by: Jonathon Reinhart <[email protected]> Signed-off-by: David S.

2021-05-04s390: fix detection of vector enhancements facility 1 vs. vector packed ↵David Hildenbrand1-2/+2
decimal facility The PoP documents: 134: The vector packed decimal facility is installed in the z/Architecture architectural mode. When bit 134 is one, bit 129 is also one. 135: The vector enhancements facility 1 is installed in the z/Architecture architectural mode. When bit 135 is one, bit 129 is also one. Looks like we confuse the vector enhancements facility 1 ("EXT") with the Vector packed decimal facility ("BCD"). Let's fix the facility checks. Detected while working on QEMU/tcg z14 support and only unlocking the vector enhancements facility 1, but not the vector packed decimal facility.

2021-05-04cifs: fix regression when mounting shares with prefix pathsPaulo Alcantara3-13/+23
The commit 315db9a05b7a ("cifs: fix leak in cifs_smb3_do_mount() ctx") revealed an existing bug when mounting shares that contain a prefix path or DFS links. cifs_setup_volume_info() requires the @devname to contain the full path (UNC + prefix) to update the fs context with the new UNC and prepath values, however we were passing only the UNC path (old_ctx->UNC) in @device thus discarding any prefix paths. Instead of concatenating both old_ctx->{UNC,prepath} and pass it in @devname, just keep the dup'ed values of UNC and prepath in cifs_sb->ctx after calling smb3_fs_context_dup(), and fix smb3_parse_devname() to correctly parse and not leak the new UNC and prefix paths.

2021-05-04vfio/mdev: remove unnecessary NULL check in mbochs_create()Dan Carpenter2-4/+1
Originally "type" could be NULL and these checks were required, but we recently changed how "type" is assigned and that's no longer the case. Now "type" points to an element in the middle of a non-NULL array. Removing the checks does not affect runtime at all, but it makes the code a little bit simpler to read.

2021-05-04xfs: don't allow log writes if the data device is readonlyDarrick J. Wong1-4/+6
While running generic/050 with an external log, I observed this warning in dmesg: Trying to write to read-only block-device sda4 (partno 4) WARNING: CPU: 2 PID: 215677 at block/blk-core.c:704 submit_bio_checks+0x256/0x510 Call Trace: submit_bio_noacct+0x2c/0x430 _xfs_buf_ioapply+0x283/0x3c0 [xfs] __xfs_buf_submit+0x6a/0x210 [xfs] xfs_buf_delwri_submit_buffers+0xf8/0x270 [xfs] xfsaild+0x2db/0xc50 [xfs] kthread+0x14b/0x170 I think this happened because we tried to cover the log after a readonly mount, and the AIL tried to write the primary superblock to the data device. The test marks the data device readonly, but it doesn't do the same to the external log device. Therefore, XFS thinks that the log is writable, even though AIL writes whine to dmesg because the data device is read only. Fix this by amending xfs_log_writable to prevent writes when the AIL can't possible write anything into the filesystem. Note: As for the external log or the rt devices being readonly-- xfs_blkdev_get will complain about that if we aren't doing a norecovery mount. Signed-off-by: Darrick J.

2021-05-04libceph: allow addrvecs with a single NONE/blank addressIlya Dryomov1-6/+14
Normally, an unused OSD id/slot is represented by an empty addrvec. However, it also appears to be possible to generate an osdmap where an unused OSD id/slot has an addrvec with a single blank address of type NONE. Allow such addrvecs and make the end result be exactly the same as for the empty addrvec case -- leave addr intact.

2021-05-04dt-bindings: net: renesas,etheravb: Fix optional second clock nameGeert Uytterhoeven1-1/+1
If the optional "clock-names" property is present, but the optional TXC reference clock is not, "make dtbs_check" complains: ethernet@e6800000: clock-names: ['fck'] is too short Fix this by declaring that a single clock name is valid. While at it, drop the superfluous upper limit on the number of clocks, as it is implied by the list of descriptions.

2021-05-04powerpc/kconfig: Restore alphabetic order of the selects under CONFIG_PPCChristophe Leroy1-17/+17
Commit a7d2475af7ae ("powerpc: Sort the selects under CONFIG_PPC") sorted all selects under CONFIG_PPC. 4 years later, several items have been introduced at wrong place, a few other have been renamed without moving them to their correct place. Reorder them now. While we are at it, simplify the test for a couple of them: - PPC_64 && PPC_PSERIES is simplified in PPC_PSERIES - PPC_64 && PPC_BOOK3S is simplified in PPC_BOOK3S_64 Signed-off-by: Christophe Leroy <[email protected]> Signed-off-by: Michael Ellerman <[email protected]> Link: https://lore.kernel.org/r/361ee3fc5009c709ae0ca592249bb0702c6ef073.1619024780.git.christophe.leroy@csgroup.eu
2021-05-04powerpc/32: Fix boot failure with CONFIG_STACKPROTECTORChristophe Leroy1-0/+3
Commit 7c95d8893fb5 ("powerpc: Change calling convention for create_branch() et. al.") complexified the frame of function do_feature_fixups(), leading to GCC setting up a stack guard when CONFIG_STACKPROTECTOR is selected. The problem is that do_feature_fixups() is called very early while 'current' in r2 is not set up yet and the code is still not at the final address used at link time. So, like other instrumentation, stack protection needs to be deactivated for feature-fixups.c and code-patching.c Fixes: 7c95d8893fb5 ("powerpc: Change calling convention for create_branch() et. al.")
