netlink: terminate outstanding dump on socket close

netlink: terminate outstanding dump on socket close
[ Upstream commit 1904fb9ebf911441f90a68e96b22aa73e4410505 ]
Netlink supports iterative dumping of data. It provides the families the following ops: - start - (optional) kicks off the dumping process - dump - actual dump helper, keeps getting called until it returns 0 - done - (optional) pairs with .start, can be used for cleanup The whole process is asynchronous and the repeated calls to .dump don't actually happen in a tight loop, but rather are triggered in response to recvmsg() on the socket.
This gives the user full control over the dump, but also means that the user can close the socket without getting to the end of the dump. To make sure .start is always paired with .done we check if there is an ongoing dump before freeing the socket, and if so call .done.
The complication is that sockets can get freed from BH and .done is allowed to sleep. So we use a workqueue to defer the call, when needed.
Unfortunately this does not work correctly. What we defer is not the cleanup but rather releasing a reference on the socket. We have no guarantee that we own the last reference, if someone else holds the socket they may release it in BH and we're back to square one.
The whole dance, however, appears to be unnecessary. Only the user can interact with dumps, so we can clean up when socket is closed. And close always happens in process context. Some async code may still access the socket after close, queue notification skbs to it etc. but no dumps can start, end or otherwise make progress.
Delete the workqueue and flush the dump state directly from the release handler. Note that further cleanup is possible in -next, for instance we now always call .done before releasing the main module reference, so dump doesn't have to take a reference of its own.

rtnetlink: change nlk->cb_mutex role
[ Upstream commit e39951d965bf58b5aba7f61dc1140dcb8271af22 ]
In commit af65bdfce98d ("[NETLINK]: Switch cb_lock spinlock to mutex and allow to override it"), Patrick McHardy used a common mutex to protect both nlk->cb and the dump() operations.
The override is used for rtnl dumps, registered with rntl_register() and rntl_register_module().
We want to be able to opt-out some dump() operations to not acquire RTNL, so we need to protect nlk->cb with a per socket mutex.
This patch renames nlk->cb_def_mutex to nlk->nl_cb_mutex
The optional pointer to the mutex used to protect dump() call is stored in nlk->dump_cb_mutex

==================== Process connector bug fixes & enhancements
Oracle DB is trying to solve a performance overhead problem it has been facing for the past 10 years and using this patch series, we can fix this issue.
Oracle DB runs on a large scale with 100000s of short lived processes, starting up and exiting quickly. A process monitoring DB daemon which tracks and cleans up after processes that have died without a proper exit needs notifications only when a process died with a non-zero exit code (which should be rare).
Due to the pmon architecture, which is distributed, each process is independent and has minimal interaction with pmon. Hence fd based solutions to track a process's spawning and exit cannot be used. Pmon needs to detect the abnormal death of a process so it can cleanup after. Currently it resorts to checking /proc every few seconds. Other methods we tried like using system call to reduce the above overhead were not accepted upstream.
With this change, we add event based filtering to proc connector module so that DB can only listen to the events it is interested in. A new event type PROC_EVENT_NONZERO_EXIT is added, which is only sent by kernel to a listening application when any process exiting has a non-zero exit status.
This change will give Oracle DB substantial performance savings - it takes 50ms to scan about 8K PIDs in /proc, about 500ms for 100K PIDs. DB does this check every 3 secs, so over an hour we save 10secs for 100K PIDs.
With this, a client can register to listen for only exit or fork or a mix or all of the events. This greatly enhances performance - currently, we need to listen to all events, and there are 9 different types of events. For eg. handling 3 types of events - 8K-forks + 8K-exits + 8K-execs takes 200ms, whereas handling 2 types - 8K-forks + 8K-exits takes about 150ms, and handling just one type - 8K exits takes about 70ms.
Measuring the time using pidfds for monitoring 8K process exits took 4 times longer - 200ms, as compared to 70ms using only exit notifications of proc connector. Hence, we cannot use pidfd for our use case.
This kind of a new event could also be useful to other applications like Google's lmkd daemon, which needs a killed process's exit notification.
This patch series is organized as follows -
Patch 1 : Needed for patch 3 to work. Patch 2 : Needed for patch 3 to work. Patch 3 : Fixes some bugs in proc connector, details in the patch. Patch 4 : Adds event based filtering for performance enhancements. Patch 5 : Allow non-root users access to proc connector events. Patch 6 : Selftest code for proc connector.
v9->v10 changes: - Rebased to net-next, re-compiled and re-tested.
v8->v9 changes: - Added sha1 ("title") of reversed patch as suggested by Eric Dumazet.
v7->v8 changes: - Fixed an issue pointed by Liam Howlett in v7.

Merge tag 'net-next-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni: "Core:
- Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the default value allows for better BIG TCP performances
- Reduce compound page head access for zero-copy data transfers
- RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when possible
- Threaded NAPI improvements, adding defer skb free support and unneeded softirq avoidance
- Address dst_entry reference count scalability issues, via false sharing avoidance and optimize refcount tracking
- Add lockless accesses annotation to sk_err[_soft]
- Optimize again the skb struct layout
- Extends the skb drop reasons to make it usable by multiple subsystems
- Better const qualifier awareness for socket casts
BPF:
- Add skb and XDP typed dynptrs which allow BPF programs for more ergonomic and less brittle iteration through data and variable-sized accesses
- Add a new BPF netfilter program type and minimal support to hook BPF programs to netfilter hooks such as prerouting or forward
- Add more precise memory usage reporting for all BPF map types
- Adds support for using {FOU,GUE} encap with an ipip device operating in collect_md mode and add a set of BPF kfuncs for controlling encap params
- Allow BPF programs to detect at load time whether a particular kfunc exists or not, and also add support for this in light skeleton
- Bigger batch of BPF verifier improvements to prepare for upcoming BPF open-coded iterators allowing for less restrictive looping capabilities
- Rework RCU enforcement in the verifier, add kptr_rcu and enforce BPF programs to NULL-check before passing such pointers into kfunc
- Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and in local storage maps
- Enable RCU semantics for task BPF kptrs and allow referenced kptr tasks to be stored in BPF maps
- Add support for refcounted local kptrs to the verifier for allowing shared ownership, useful for adding a node to both the BPF list and rbtree
- Add BPF verifier support for ST instructions in convert_ctx_access() which will help new -mcpu=v4 clang flag to start emitting them
- Add ARM32 USDT support to libbpf
- Improve bpftool's visual program dump which produces the control flow graph in a DOT format by adding C source inline annotations
Protocols:
- IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value indicates the provenance of the IP address
- IPv6: optimize route lookup, dropping unneeded R/W lock acquisition
- Add the handshake upcall mechanism, allowing the user-space to implement generic TLS handshake on kernel's behalf
- Bridge: support per-{Port, VLAN} neighbor suppression, increasing resilience to nodes failures
- SCTP: add support for Fair Capacity and Weighted Fair Queueing schedulers
- MPTCP: delay first subflow allocation up to its first usage. This will allow for later better LSM interaction
- xfrm: Remove inner/outer modes from input/output path. These are not needed anymore
- WiFi: - reduced neighbor report (RNR) handling for AP mode - HW timestamping support - support for randomized auth/deauth TA for PASN privacy - per-link debugfs for multi-link - TC offload support for mac80211 drivers - mac80211 mesh fast-xmit and fast-rx support - enable Wi-Fi 7 (EHT) mesh support
Netfilter:
- Add nf_tables 'brouting' support, to force a packet to be routed instead of being bridged
- Update bridge netfilter and ovs conntrack helpers to handle IPv6 Jumbo packets properly, i.e. fetch the packet length from hop-by-hop extension header. This is needed for BIT TCP support
- The iptables 32bit compat interface isn't compiled in by default anymore
- Move ip(6)tables builtin icmp matches to the udptcp one. This has the advantage that icmp/icmpv6 match doesn't load the iptables/ip6tables modules anymore when iptables-nft is used
- Extended netlink error report for netdevice in flowtables and netdev/chains. Allow for incrementally add/delete devices to netdev basechain. Allow to create netdev chain without device
Driver API:
- Remove redundant Device Control Error Reporting Enable, as PCI core has already error reporting enabled at enumeration time
- Move Multicast DB netlink handlers to core, allowing devices other then bridge to use them
- Allow the page_pool to directly recycle the pages from safely localized NAPI
- Implement lockless TX queue stop/wake combo macros, allowing for further code de-duplication and sanitization
- Add YNL support for user headers and struct attrs
- Add partial YNL specification for devlink
- Add partial YNL specification for ethtool
- Add tc-mqprio and tc-taprio support for preemptible traffic classes
- Add tx push buf len param to ethtool, specifies the maximum number of bytes of a transmitted packet a driver can push directly to the underlying device
- Add basic LED support for switch/phy
- Add NAPI documentation, stop relaying on external links
- Convert dsa_master_ioctl() to netdev notifier. This is a preparatory work to make the hardware timestamping layer selectable by user space
- Add transceiver support and improve the error messages for CAN-FD controllers
