* Rework check for libclang_rt to see if the needed library exists.Bryan Drewery2018-06-271-18/+9
| | | | | | | | | | | | | | | | Currently libclang_rt is not provided for cross-building and as such is not connected to cross-tools. For building clang once in universe it is likely that libclang_rt won't exist for the universe toolchain but even if it did it would not support anything but the native arch. So explicitly check for support before enabling h_raw.

* Reimplement brk() and sbrk() to avoid the use of _end.Mark Johnston2018-06-042-0/+150
| | | | | | | | | | | | | | | | | | | | | | | | | Previously, libc.so would initialize its notion of the break address using _end, a special symbol emitted by the static linker following the bss section. Compatibility issues between lld and ld.bfd could cause the wrong definition of _end (libc.so's definition rather than that of the executable) to be used, breaking the brk()/sbrk() interface. Avoid this problem and future interoperability issues by simply not relying on _end. Instead, modify the break() system call to return the kernel's view of the current break address, and have libc initialize its state using an extra syscall upon the first use of the interface. As a side effect, this appears to fix brk()/sbrk() usage in executables run with rtld direct exec, since the kernel and libc.so no longer maintain separate views of the process' break address.

* getentropy(3): Fallback to kern.arandom sysctl on older kernelsConrad Meyer2018-03-211-0/+3
| | | | | | | | | | | | | | | | | | | On older kernels, when userspace program disables SIGSYS, catch ENOSYS and emulate getrandom(2) syscall with the kern.arandom sysctl (via existing arc4_sysctl wrapper). Special care is taken to faithfully emulate EFAULT on NULL pointers, because sysctl(3) as used by kern.arandom ignores NULL oldp. (This was caught by getentropy(3) ATF tests.)

* Implement getrandom(2) and getentropy(3)Conrad Meyer2018-03-212-0/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The general idea here is to provide userspace programs with well-defined sources of entropy, in a fashion that doesn't require opening a new file descriptor (ulimits) or accessing paths (/dev/urandom may be restricted by chroot or capsicum). getrandom(2) is the more general API, and comes from the Linux world. Since our urandom and random devices are identical, the GRND_RANDOM flag is ignored. getentropy(3) is added as a compatibility shim for the OpenBSD API. truss(1) support is included. Tests for both system calls are provided. Coverage is believed to be at least as comprehensive as LTP getrandom(2) test coverage. Additionally, instructions for running the LTP tests directly against FreeBSD are provided in the "Test Plan" section of the Differential revision linked below. (They pass, of course.)

* Add libregex, connect it to the buildKyle Evans2018-01-222-58/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libregex is a regex(3) implementation intended to feature GNU extensions and any other non-POSIX compliant extensions that are deemed worthy. These extensions are separated out into a separate library for the sake of not cluttering up libc further with them as well as not deteriorating the speed (or lack thereof) of the libc implementation. libregex is implemented as a build of the libc implementation with LIBREGEX defined to distinguish this from a libc build. The reasons for implementation like this are two-fold: 1.) Maintenance- This reduces the overhead induced by adding yet another regex implementation to base. 2.) Ease of use- Flipping on GNU extensions will be as simple as linking against libregex, and POSIX-compliant compilations can be guaranteed with a REG_POSIX cflag that should be ignored by libc/regex and disables extensions in libregex. It is also easier to keep REG_POSIX sane and POSIX pure when implemented in this fashion. Tests are added for future functionality, but left disconnected for the time being while other testing is done.

* Optimize telldir(3)Alan Somers2017-12-062-2/+192
| | | | | | | | | | | | | | | | | | | | | | | | | Currently each call to telldir() requires a malloc and adds an entry to a linked list which must be traversed on future telldir(), seekdir(), closedir(), and readdir() calls. Applications that call telldir() for every directory entry incur O(n^2) behavior in readdir() and O(n) in telldir() and closedir(). This optimization eliminates the malloc() and linked list in most cases by packing the relevant information into a single long. On 64-bit architectures msdosfs, NFS, tmpfs, UFS, and ZFS can all use the packed representation. On 32-bit architectures msdosfs, NFS, and UFS can use the packed representation, but ZFS and tmpfs can only use it for about the first 128 files per directory. Memory savings is about 50 bytes per telldir(3) call. Speedup for telldir()-heavy directory traversals is about 20-30x for one million files per directory.

* getmntinfo(3): Scale faster, and return soonerConrad Meyer2017-08-252-0/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | | | getmntinfo(3) is designed around a relatively static or slow growing set of current mounts. It tried to detect a race with somewhat concurrent mount and re-call getfsstat(2) in that case, looping indefinitely. It also allocated space for a single extra mount as slop. In the case where the user has a large number of mounts and is adding them at a rapid pace, it fell over. This patch makes two functional changes: 1. Allocate even more slop. Double whatever the last getfsstat(2) returned. 2. Abort and return some known results after looping a few times (arbitrarily, 3). If the list is constantly changing, we can't guarantee we return a full result to the user at any point anyways. While here, add very basic functional tests for getmntinfo(3) to the libc suite.

| | | | | | | | | | | | | | | | | | | | abort_handler_s() currently simply calls abort(), though the standard specifies more: "Writes an implementation-defined message to stderr which must include the string pointed to by msg and calls abort()." memset_s() is missing error condition "n > smax", and does not invoke the constraint handler after filling the buffer: "following errors are detected at runtime and call the currently installed constraint handler function after storing ch in every location of the destination range [dest, dest+destsz) if dest and destsz are themselves valid", one of the errors is "n > smax" itself.

This is also what Linux does. (NetBSD updates rmtp unconditionally.) Copy the whole nanosleep.2 man page from NetBSD because it is complete and closely resembles the POSIX description.
