When doing a route dump across all address families, do not error out if the table does not exist. This allows a route dump for AF_UNSPEC with a table id that may only exist for some of the families. Do return the table does not exist error if dumping routes for a specific family and the table does not exist. Signed-off-by: NDavid Ahern <dsahern@gmail.com> Signed-off-by: NDavid S.

Preliminary results show eg. more files/sec in fsmark, better perf on multi-threaded workloads (filebench, dbench), fewer context switches and overall better memory allocation characteristics (multiple benchmarks). Apart from general performance, there's an improvement for qgroups + balance workload that's been troubling our users. Note for stable: there are 20+ patches tagged for stable, out of 90. Not all of them apply cleanly on all stable versions but the conflicts are mostly due to simple cleanups and resolving should be obvious. The fixes are otherwise independent. Performance improvements: - transition between blocking and spinning modes of path is gone, which originally resulted to more unnecessary wakeups and updates to the path locks, the effects are measurable and improve latency and scalability - qgroups: first batch of changes that should speedup balancing with qgroups on, skip quota accounting on unchanged subtrees, overall gain is about 30+% in runtime - use rb-tree with cached first node for several structures, small improvement to avoid pointer chasing Fixes: - trim - fix: some blockgroups could have been missed if their logical address was past the total filesystem size (ie. after a lot of balancing) - better error reporting, after processing blockgroups and whole device - fix: continue trimming block groups after an error is encountered - check for trim support of the device earlier and avoid some unnecessary work - less interaction with transaction commit that improves latency on slower storage (eg. image files over NFS) - fsync - fix warning when replaying log after fsync of a O_TMPFILE - fix wrong dentries after fsync of file that got its parent replaced - qgroups: fix rescan that might misc some dirty groups - don't clean dirty pages during buffered writes, this could lead to lost updates in some corner cases - some block groups could have been delayed in creation, if the allocation triggered another one - error handling improvements Cleanups: - removed unused struct members and variables - function return type cleanups - delayed refs code refactoring - protect against deadlock that could be caused by crafted image that tries to allocate from a tree that's locked already" * tag 'for-4.20-part1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (93 commits) btrfs: switch return_bigger to bool in find_ref_head btrfs: remove fs_info from btrfs_should_throttle_delayed_refs btrfs: remove fs_info from btrfs_check_space_for_delayed_refs btrfs: delayed-ref: pass delayed_refs directly to btrfs_delayed_ref_lock btrfs: delayed-ref: pass delayed_refs directly to btrfs_select_ref_head btrfs: qgroup: move the qgroup->members check out from (!qgroup)'s else branch btrfs: relocation: Remove redundant tree level check btrfs: relocation: Cleanup while loop using rbtree_postorder_for_each_entry_safe btrfs: qgroup: Avoid calling qgroup functions if qgroup is not enabled Btrfs: fix wrong dentries after fsync of file that got its parent replaced Btrfs: fix warning when replaying log after fsync of a tmpfile btrfs: drop min_size from evict_refill_and_join btrfs: assert on non-empty delayed iputs btrfs: make sure we create all new block groups btrfs: reset max_extent_size on clear in a bitmap btrfs: protect space cache inode alloc with GFP_NOFS btrfs: release metadata before running delayed refs Btrfs: kill btrfs_clear_path_blocking btrfs: dev-replace: remove pointless assert in write unlock btrfs: dev-replace: move replace members out of fs_info ...

Merge branch 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull siginfo updates from Eric Biederman: "I have been slowly sorting out siginfo and this is the culmination of that work. The primary result is in several ways the signal infrastructure has been made less error prone. The code has been updated so that manually specifying SEND_SIG_FORCED is never necessary. The conversion to the new siginfo sending functions is now complete, which makes it difficult to send a signal without filling in the proper siginfo fields. At the tail end of the patchset comes the optimization of decreasing the size of struct siginfo in the kernel from 128 bytes to about 48 bytes on 64bit. The fundamental observation that enables this is by definition none of the known ways to use struct siginfo uses the extra bytes. This comes at the cost of a small user space observable difference. For the rare case of siginfo being injected into the kernel only what can be copied into kernel_siginfo is delivered to the destination, the rest of the bytes are set to 0. For cases where the signal and the si_code are known this is safe, because we know those bytes are not used. For cases where the signal and si_code combination is unknown the bits that won't fit into struct kernel_siginfo are tested to verify they are zero, and the send fails if they are not. I made an extensive search through userspace code and I could not find anything that would break because of the above change. If it turns out I did break something it will take just the revert of a single change to restore kernel_siginfo to the same size as userspace siginfo. Testing did reveal dependencies on preferring the signo passed to sigqueueinfo over si->signo, so bit the bullet and added the complexity necessary to handle that case. Testing also revealed bad things can happen if a negative signal number is passed into the system calls. Something no sane application will do but something a malicious program or a fuzzer might do. So I have fixed the code that performs the bounds checks to ensure negative signal numbers are handled" * 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (80 commits) signal: Guard against negative signal numbers in copy_siginfo_from_user32 signal: Guard against negative signal numbers in copy_siginfo_from_user signal: In sigqueueinfo prefer sig not si_signo signal: Use a smaller struct siginfo in the kernel signal: Distinguish between kernel_siginfo and siginfo signal: Introduce copy_siginfo_from_user and use it's return value signal: Remove the need for __ARCH_SI_PREABLE_SIZE and SI_PAD_SIZE signal: Fail sigqueueinfo if si_signo != sig signal/sparc: Move EMT_TAGOVF into the generic siginfo.h signal/unicore32: Use force_sig_fault where appropriate signal/unicore32: Generate siginfo in ucs32_notify_die signal/unicore32: Use send_sig_fault where appropriate signal/arc: Use force_sig_fault where appropriate signal/arc: Push siginfo generation into unhandled_exception signal/ia64: Use force_sig_fault where appropriate signal/ia64: Use the force_sig(SIGSEGV,...) in ia64_rt_sigreturn signal/ia64: Use the generic force_sigsegv in setup_frame signal/arm/kvm: Use send_sig_mceerr signal/arm: Use send_sig_fault where appropriate signal/arm: Use force_sig_fault where appropriate ...

The networking merge brought in the experimental support for the Qualcomm ath10k system NOC, which selects QCOM_QMI_HELPERS as a dependency. But the ATH10K_SNOC option (which selects QCOM_QMI_HELPERS) depends on ARCH_QCOM || COMPILE_TEST in order to get wider build testing than just the unusual QCOM architecture build, while the QCOM_QMI_HELPERS option doesn't have that COMPILE_TEST option and is limited to only ARCH_QCOM.

With EDT model, SRTT no longer is inflated by pacing delays. This means that RTO and some other xmit timers might be setup incorrectly. This is particularly visible with either : - Very small enforced pacing rates (SO_MAX_PACING_RATE) - Reduced rto (from the default 200 ms) This can lead to TCP flows aborts in the worst case, or spurious retransmits in other cases. For example, this session gets far more throughput than the requested 80kbit : $ netperf -H 127.0.0.2 -l 100 -- -q 10000 MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.2 () port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 540000 262144 262144 104.00 2.66 With the fix : $ netperf -H 127.0.0.2 -l 100 -- -q 10000 MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.2 () port 0 AF_INET Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 540000 262144 262144 104.00 0.12 EDT allows for better control of rtx timers, since TCP has a better idea of the earliest departure time of each skb in the rtx queue. We only have to eventually add to the timer the difference of the EDT time with current time. Signed-off-by: NEric Dumazet <edumazet@google.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This reverts commit dd979b4d. This broke tcp_poll for SMC fallback: An AF_SMC socket establishes an internal TCP socket for the initial handshake with the remote peer. Whenever the SMC connection can not be established this TCP socket is used as a fallback. All socket operations on the SMC socket are then forwarded to the TCP socket. In case of poll, the file->private_data pointer references the SMC socket because the TCP socket has no file assigned. This causes tcp_poll to wait on the wrong socket.

There is a compatibility issue between RTL8211E implemented in Developerbox and netsec ethernet controller IP. Our MDIO controller stops MDC clock right after the write access, but RTL8211E expects MDC clock must be kept toggling for several clock cycle with MDIO high before entering the IDLE state. Without keeping clock after write access, write access is not correctly handled and register is not updated. To meet this requirement, netsec driver needs to issue dummy read(e.g. read PHYID1(offset 0x2) register) right after write access, to keep MDC clock. We think this compatibility issue is a problem specific to our MDIO controller and RTL8211E.

In ndo_stop, driver resets the netsec ethernet controller IP. When the netsec IP is reset, HW running mode turns to NRM mode and driver has to wait until this mode transition completes. But mode transition to NRM will not complete if the PHY is in normal operation state. Netsec IP requires PHY is in power down state when it is reset. This modification stops the PHY before resetting netsec. Together with this modification, phy_addr is stored in netsec_priv structure because ndev->phydev is not yet ready in ndo_init.
