2022-07-19amt: use workqueue for gateway side message handlingTaehee Yoo
There are some synchronization issues(amt->status, amt->req_cnt, etc) if the interface is in gateway mode because gateway message handlers are processed concurrently. This applies a work queue for processing these messages instead of expanding the locking context. So, the purposes of this patch are to fix exist race conditions and to make gateway to be able to validate a gateway status more correctly. When the AMT gateway interface is created, it tries to establish to relay. The establishment step looks stateless, but it should be managed well. In order to handle messages in the gateway, it saves the current status(i.e. AMT_STATUS_XXX). This patch makes gateway code to be worked with a single thread. Now, all messages except the multicast are triggered(received or delay expired), and these messages will be stored in the event queue(amt->events). Then, the single worker processes stored messages asynchronously one by one. The multicast data message type will be still processed immediately. Now, amt->lock is only needed to access the event queue(amt->events) if an interface is the gateway mode.

2022-07-15tcp/udp: Make early_demux back namespacified.Kuniyuki Iwashima
Commit e21145a9871a ("ipv4: namespacify ip_early_demux sysctl knob") made it possible to enable/disable early_demux on a per-netns basis. Then, we introduced two knobs, tcp_early_demux and udp_early_demux, to switch it for TCP/UDP in commit dddb64bcb346 ("net: Add sysctl to toggle early demux for tcp and udp"). However, the .proc_handler() was wrong and actually disabled us from changing the behaviour in each netns. We can execute early_demux if net.ipv4.ip_early_demux is on and each proto .early_demux() handler is not NULL. When we toggle (tcp|udp)_early_demux, the change itself is saved in each netns variable, but the .early_demux() handler is a global variable, so the handler is switched based on the init_net's sysctl variable. Thus, netns (tcp|udp)_early_demux knobs have nothing to do with the logic. Whether we CAN execute proto .early_demux() is always decided by init_net's sysctl knob, and whether we DO it or not is by each netns ip_early_demux knob. This patch namespacifies (tcp|udp)_early_demux again. For now, the users of the .early_demux() handler are TCP and UDP only, and they are called directly to avoid retpoline. So, we can remove the .early_demux() handler from inet6?_protos and need not dereference them in ip6?_rcv_finish_core(). If another proto needs .early_demux(), we can restore it at that time.

2022-07-08net: Fix data-races around sysctl_mem.Kuniyuki Iwashima
While reading .sysctl_mem, it can be changed concurrently. So, we need to add READ_ONCE() to avoid data-races. Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Signed-off-by: Kuniyuki Iwashima <kuniyu@amazon.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-07-08net: sock: tracing: Fix sock_exceed_buf_limit not to dereference stale pointerSteven Rostedt (Google)
The trace event sock_exceed_buf_limit saves the prot->sysctl_mem pointer and then dereferences it in the TP_printk() portion. This is unsafe as the TP_printk() portion is executed at the time the buffer is read. That is, it can be seconds, minutes, days, months, even years later. If the proto is freed, then this dereference will can also lead to a kernel crash. Instead, save the sysctl_mem array into the ring buffer and have the TP_printk() reference that instead. This is the proper and safe way to read pointers in trace events.

2022-07-08bpf: Add flags arg to bpf_dynptr_read and bpf_dynptr_write APIsJoanne Koong
Commit 13bbbfbea759 ("bpf: Add bpf_dynptr_read and bpf_dynptr_write") added the bpf_dynptr_write() and bpf_dynptr_read() APIs. However, it will be needed for some dynptr types to pass in flags as well (e.g. when writing to a skb, the user may like to invalidate the hash or recompute the checksum). This patch adds a "u64 flags" arg to the bpf_dynptr_read() and bpf_dynptr_write() APIs before their UAPI signature freezes where we then cannot change them anymore with a 5.19.x released kernel.

2022-07-07fbcon: Prevent that screen size is smaller than font sizeHelge Deller
We need to prevent that users configure a screen size which is smaller than the currently selected font size. Otherwise rendering chars on the screen will access memory outside the graphics memory region. This patch adds a new function fbcon_modechange_possible() which implements this check and which later may be extended with other checks if necessary. The new function is called from the FBIOPUT_VSCREENINFO ioctl handler in fbmem.c, which will return -EINVAL if userspace asked for a too small screen size.

Offloading police with action TC_ACT_UNSPEC was erroneously disabled even though it was supported by mlx5 matchall offload implementation, which didn't verify the action type but instead assumed that any single police action attached to matchall classifier is a 'continue' action. Lack of action type check made it non-obvious what mlx5 matchall implementation actually supports and caused implementers and reviewers of referenced commits to disallow it as a part of improved validation code.
