2020-07-15Merge branch 'mlxsw-reg-add-policer-bandwidth-limits'Jakub Kicinski
Ido Schimmel says: ==================== mlxsw: Offload tc police action This patch set adds support for tc police action in mlxsw. Patches #1-#2 add defines for policer bandwidth limits and resource identifiers (e.g., maximum number of policers). Patch #3 adds a common policer core in mlxsw. Currently it is only used by the policy engine, but future patch sets will use it for trap policers and storm control policers. The common core allows us to share common logic between all policer types and abstract certain details from the various users in mlxsw. Patch #4 exposes the maximum number of supported policers and their current usage to user space via devlink-resource. This provides better visibility and also used for selftests purposes. Patches #5-#7 gradually add support for tc police action in the policy engine by calling into previously mentioned policer core. Patch #8 adds a generic selftest for tc-police that can be used with veth pairs or physical loopbacks. Patches #9-#11 add mlxsw-specific selftests. ==================== Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2020-07-15mlxsw: core_acl_flex_actions: Work around hardware limitationIdo Schimmel
In the policy engine, each ACL rule points to an action block where the ACL actions are stored. Each action block consists of one or more action sets. Each action set holds one or more individual actions, up to a maximum queried from the device. For example: Action set #1 Action set #2 +----------+ +--------------+ +--------------+ | ACL rule +----------> Action #1 | +-----> Action #4 | +----------+ +--------------+ | +--------------+ | Action #2 | | | Action #5 | +--------------+ | +--------------+ | Action #3 +------+ | | +--------------+ +--------------+ <---------+ Action block +-----------------> The hardware has a limitation that prevents a policing action (MLXSW_AFA_POLCNT_CODE when used with a policer, not a counter) from being configured in the same action set with a trap action (i.e., MLXSW_AFA_TRAP_CODE or MLXSW_AFA_TRAPWU_CODE). Note that the latter used to implement multiple actions: 'trap', 'mirred', 'drop'. Work around this limitation by teaching mlxsw_afa_block_append_action() to create a new action set not only when there is no more room left in the current set, but also when there is a conflict between previously mentioned actions.

2020-07-15afs: Fix interruption of operationsDavid Howells
The afs filesystem driver allows unstarted operations to be cancelled by signal, but most of these can easily be restarted (mkdir for example). The primary culprits for reproducing this are those applications that use SIGALRM to display a progress counter. File lock-extension operation is marked uninterruptible as we have a limited time in which to do it, and the release op is marked uninterruptible also as if we fail to unlock a file, we'll have to wait 20 mins before anyone can lock it again. The store operation logs a warning if it gets interruption, e.g.: kAFS: Unexpected error from FS.StoreData -4 because it's run from the background - but it can also be run from fdatasync()-type things. However, store options aren't marked interruptible at the moment. Fix this in the following ways: (1) Mark store operations as uninterruptible. It might make sense to relax this for certain situations, but I'm not sure how to make sure that background store ops aren't affected by signals to foreground processes that happen to trigger them. (2) In afs_get_io_locks(), where we're getting the serialisation lock for talking to the fileserver, return ERESTARTSYS rather than EINTR because a lot of the operations (e.g. mkdir) are restartable if we haven't yet started sending the op to the server.

2020-07-16ovl: fix regression with re-formatted lower squashfsAmir Goldstein
Commit 9df085f3c9a2 ("ovl: relax requirement for non null uuid of lower fs") relaxed the requirement for non null uuid with single lower layer to allow enabling index and nfs_export features with single lower squashfs. Fabian reported a regression in a setup when overlay re-uses an existing upper layer and re-formats the lower squashfs image. Because squashfs has no uuid, the origin xattr in upper layer are decoded from the new lower layer where they may resolve to a wrong origin file and user may get an ESTALE or EIO error on lookup. To avoid the reported regression while still allowing the new features with single lower squashfs, do not allow decoding origin with lower null uuid unless user opted-in to one of the new features that require following the lower inode of non-dir upper (index, xino, metacopy).

2020-07-16ovl: relax WARN_ON() when decoding lower directory file handleAmir Goldstein
Decoding a lower directory file handle to overlay path with cold inode/dentry cache may go as follows: 1. Decode real lower file handle to lower dir path 2. Check if lower dir is indexed (was copied up) 3. If indexed, get the upper dir path from index 4. Lookup upper dir path in overlay 5. If overlay path found, verify that overlay lower is the lower dir from step 1 On failure to verify step 5 above, user will get an ESTALE error and a WARN_ON will be printed. A mismatch in step 5 could be a result of lower directory that was renamed while overlay was offline, after that lower directory has been copied up and indexed. This is a scripted reproducer based on xfstest overlay/052: # Create lower subdir create_dirs create_test_files $lower/lowertestdir/subdir mount_dirs # Copy up lower dir and encode lower subdir file handle touch $SCRATCH_MNT/lowertestdir test_file_handles $SCRATCH_MNT/lowertestdir/subdir -p -o $tmp.fhandle # Rename lower dir offline unmount_dirs mv $lower/lowertestdir $lower/lowertestdir.new/ mount_dirs # Attempt to decode lower subdir file handle test_file_handles $SCRATCH_MNT -p -i $tmp.fhandle Since this WARN_ON() can be triggered by user we need to relax it.

2020-07-15netfilter: nf_tables: fix nat hook table deletionFlorian Westphal
sybot came up with following transaction: add table ip syz0 add chain ip syz0 syz2 { type nat hook prerouting priority 0; policy accept; } add table ip syz0 { flags dormant; } delete chain ip syz0 syz2 delete table ip syz0 which yields: hook not found, pf 2 num 0 WARNING: CPU: 0 PID: 6775 at net/netfilter/core.c:413 __nf_unregister_net_hook+0x3e6/0x4a0 net/netfilter/core.c:413 [..] nft_unregister_basechain_hooks net/netfilter/nf_tables_api.c:206 [inline] nft_table_disable net/netfilter/nf_tables_api.c:835 [inline] nf_tables_table_disable net/netfilter/nf_tables_api.c:868 [inline] nf_tables_commit+0x32d3/0x4d70 net/netfilter/nf_tables_api.c:7550 nfnetlink_rcv_batch net/netfilter/nfnetlink.c:486 [inline] nfnetlink_rcv_skb_batch net/netfilter/nfnetlink.c:544 [inline] nfnetlink_rcv+0x14a5/0x1e50 net/netfilter/nfnetlink.c:562 netlink_unicast_kernel net/netlink/af_netlink.c:1303 [inline] Problem is that when I added ability to override base hook registration to make nat basechains register with the nat core instead of netfilter core, I forgot to update nft_table_disable() to use that instead of the 'raw' hook register interface. In syzbot transaction, the basechain is of 'nat' type. Its registered with the nat core. The switch to 'dormant mode' attempts to delete from netfilter core instead. After updating nft_table_disable/enable to use the correct helper, nft_(un)register_basechain_hooks can be folded into the only remaining caller. Because nft_trans_table_enable() won't do anything when the DORMANT flag is set, remove the flag first, then re-add it in case re-enablement fails, else this patch breaks sequence: add table ip x { flags dormant; } /* add base chains */ add table ip x The last 'add' will remove the dormant flags, but won't have any other effect -- base chains are not registered. Then, next 'set dormant flag' will create another 'hook not found' splat.

2020-07-15iwlegacy: Check the return value of pcie_capability_read_*()Bolarinwa Olayemi Saheed
On failure pcie_capability_read_dword() sets it's last parameter, val to 0. However, with Patch 14/14, it is possible that val is set to ~0 on failure. This would introduce a bug because (x & x) == (~0 & x). This bug can be avoided without changing the function's behaviour if the return value of pcie_capability_read_dword is checked to confirm success. Check the return value of pcie_capability_read_dword() to ensure success.

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.
