* vfs: add realpathat syscallMateusz Guzik2020-02-201-1/+1
| | | | | | | | | | | | | | | | | | realpath(3) is used a lot e.g., by clang and is a major source of getcwd and fstatat calls. This can be done more efficiently in the kernel. This works by performing a regular lookup while saving the name and found parent directory. If the terminal vnode is a directory we can resolve it using usual means. Otherwise we can use the name saved by lookup and resolve the parent. See the review for sample syscall counts.

* Use sigfastblock(2) in rtld.Konstantin Belousov2020-02-094-43/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | This allows for rtld to not issue two sigprocmask(2) syscalls for each symbol binding operation in single-threaded processes. Rtld needs to block signals as part of locking to ensure signal safety of the bind process, because signal handlers might need to lazily resolve symbol references. As result, number of syscalls issued on startup by simple programs not using libthr, is typically reduced 2x. For instance, for hello world, I see: non-sigfastblock # (truss ./hello > /dev/null) |& wc -l 63 sigfastblock # (truss ./hello > /dev/null) |& wc -l 37 Tested by: pho Disscussed with: cem, emaste, jilles Sponsored by: The FreeBSD Foundation Differential revision: https://reviews.freebsd.org/D12773 Notes: svn path=/head/; revision=357697

* rtld: Fix segfault in direct exec modeRyan Stone2020-01-071-2/+3
| | | | | | | | | | | | | | | | | | | | When rtld is directly executed with arguments, it has to move the program arguments, environment and elf aux data up a few slots to remove its own arguments before the process being executed sees them. When copying the environment, rtld was incorrectly testing whether the location about to be written to currently contained NULL, when was supposed to check whether it had just copied the NULL terminator of the environment string. This had the result that the ELF aux data was mostly treated as environment variables, and rtld would quickly crash when it tried to access required ELF aux data that it didn't think was present.

| | | | | | | | | | | | | | | | | | | When activated in direct exec mode, kernel-provided AT_EXECPATH points to the interpreter. We need to recalculate auxv to point to the string with the path to the executable which is actually executed. The somewhat problematic case is when the executable path is relative and either $PATH use is not enabled or it contains '/' so $PATH search is not performed. In this case resulting AT_EXECPATH is relative, I might fix this later.

A PT_LOAD with zero p_filesz is legal (but somewhat uncommon due to segment merging in modern linkers, as it is more efficient to merge .data and .bss by just extending p_memsz in the previous segment, assuming compatible page protection.)

This involves creating a new file that holds the entropy and renaming of all existing entropy files. However, the entropy data do not really need to be kept in a particular order, and replacing the oldest file is sufficient. This commit replaces the rotation with a scan in the [1..entropy_save_num] space that finds the first empty slot, or the slot of the oldest file, and writes entropy into that slot. This also fixes an issue that prevents save-entropy from saving any entropy when there is one non-regular file in any slot as a side effect. Based on an earlier patch from peterj@.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | FreeBSDlua ("flua") is a FreeBSD-private lua, flavored with whatever extensions we need for base system operations. We currently support a subset of lfs and lposix that are used in the rewrite of makesyscall.sh into lua, added in r354786. flua is intentionally written such that one can install standard lua and some set of lua modules from ports and achieve the same effect. linit_flua is a copy of linit.c from contrib/lua with lfs and lposix added in. This is similar to what we do in stand/. linit.c has been renamed to make it clear that this has flua-specific bits. luaconf has been slightly obfuscated to make extensions more difficult. Part of the problem is that flua is already hard enough to use as a bootstrap tool because it's not in PATH- attempting to do extension loading would require a special bootstrap version of flua with paths changed to protect the innocent. src.lua.mk has been added to make it easy for in-tree stuff to find flua, whether it's bootstrap-flua or relying on PATH frobbing by Makefile.inc1.
