Gleb Smirnoff	d88eb4654f	tcp: address a wire level race with 2 ACKs at the end of TCP handshake Imagine we are in SYN-RCVD state and two ACKs arrive at the same time, both valid, e.g. coming from the same host and with valid sequence. First packet would locate the listening socket in the inpcb database, write-lock it and start expanding the syncache entry into a socket. Meanwhile second packet would wait on the write lock of the listening socket. First packet will create a new ESTABLISHED socket, free the syncache entry and unlock the listening socket. Second packet would call into syncache_expand(), but this time it will fail as there is no syncache entry. Second packet would generate RST, effectively resetting the remote connection. It seems to me, that it is impossible to solve this problem with just rearranging locks, as the race happens at a wire level. To solve the problem, for an ACK packet arrived on a listening socket, that failed syncache lookup, perform a second non-wildcard lookup right away. That lookup may find the new born socket. Otherwise, we indeed send RST. Tested by: kp Reviewed by: tuexen, rrs PR: 265154 Differential revision: https://reviews.freebsd.org/D36066	8 hours ago
Alexander V. Chernikov	f998535a66	netinet6: allow ND entries creation for all directly-reachable destinations. The current assumption is that kernel-handled rtadv prefixes along with the interface address prefixes are the only prefixes considered in the ND neighbor eligibility code. Change this by allowing any non-gatewaye routes to be eligible. This will allow DHCPv6-controlled routes to be correctly handled by the ND code. Refactor nd6_is_new_addr_neighbor() to enable more deterministic performance in "found" case and remove non-needed V_rt_add_addr_allfibs handling logic.

Mark Johnston	3ba8e9dc4a	dtrace/amd64: Implement emulation of call instructions Here, the provider is responsible for updating the trapframe to redirect control flow and for computing the return address. Once software-saved registers are restored, the emulation shifts the remaining context down on the stack to make space for the return address, then copies the address provided by the invop handler. dtrace_invop() is modified to allocate temporary storage space on the stack for use by the provider to return the return address. This is to support a new provider for amd64 which can instrument arbitrary instructions, not just function entry and exit instructions as FBT does.

Jessica Clarke	febca0e643	etcupdate: Add a -N flag to perform a NO_ROOT build This is in preparation for including an etcupdate tree when performing a -DNO_ROOT release image build. Although -DNO_ROOT can be passed via -M, to be useful we need to mangle the resulting METALOG to mirror the various cleanups to the tree that are done after the build (removing generated files, empty files and empty directories), so etcupdate needs its own flag.

Jessica Clarke	c5e30fbdb7	etcupdate: Prefer POSIX -depth to BSD -d This is in preparation for building an etcupdate tree on non-FreeBSD when building release images. The -d option is documented as a BSD-specific equivalent to the POSIX -depth primary. Whilst GNU find sort of accepts it in an attempt to be compatible, it still doesn't permit it coming before the paths, unlike BSD find, and prints a deprecation warning either way. Thus, use the equivalent POSIX -depth to ensure it works correctly and without warning everywhere.

Jessica Clarke	e9ba25aabf	release: Use in-tree etcupdate for build This is in preparation for non-FreeBSD and -DNO_ROOT builds. On non-FreeBSD there is no host etcupdate to use, and -DNO_ROOT will require additional flags that may not be supported by the host's etcupdate when building on FreeBSD. Moreover, there's no guarantee anyway that the host's etcupdate is quite right for the current tree; upgrading from source only requires that the host's is good enough for -p which just manually copies master.passwd and group, the rest of the upgrade is done post-installworld. For example, should a new set of autogenerated files be added that etcupdate is taught about, the host won't know about them and so the bootstrapped current tree will incorrectly contain them, leading to spurious diffs on the installed system.

Mark Johnston	5c50e900ad	vm_fault: Shoot down shared mappings in vm_fault_copy_entry() As in vm_fault_cow(), it's possible, albeit rare, for multiple vm_maps to share a shadow object. When copying a page from a backing object into the shadow, all mappings of the source page must therefore be removed. Otherwise, future operations on the object tree may detect that the source page is fully shadowed and thus can be freed.

Konstantin Belousov	00d17cf342	elf_note_prpsinfo: handle more failures from proc_getargv() Resulting sbuf_len() from proc_getargv() might return 0 if user mangled ps_strings enough. Also, sbuf_len() API contract is to return -1 if the buffer overflowed. The later should not occur because get_ps_strings() checks for catenated length, but check for this subtle detail explicitly as well to be more resilent.

So, libcxxrt uses an assembly stub which preserves caller-saved registers around the call to __cxa_get_cleanup(). But: - it failed to restore them properly, - it did not preserve the link register. Fix both of these problems. This is needed to fix exception unwinding on FreeBSD with LLVM 14. Note that r4 is callee-saved but is pushed onto the stack to preserve stack pointer alignment.
