2021-10-26syscalls: Gracefully handle failure to load libc's libutil....In particular, libutil is not found when running code on a statically-linked Guile. Reported by mahmooz on #guix. * guix/build/syscalls.scm (syscall->procedure): Add #:library parameter and honor it.

(resume-if-hibernated): Reuse DEVICE-NUMBER->MAJOR+MINOR. Tobias Geerinckx-Rice
2021-07-07Revert "syscalls: 'terminal-dimension' ignores EPERM."...This reverts commit 17a102332a253f0e3b1f511fa7bda2094264a77c. See <https://github.com/koverstreet/bcachefs/pull/277>. Tobias Geerinckx-Rice
2021-03-23syscalls: Fix RNDADDTOENTCNT on powerpc64le-linux....This fixes the failing test add-to-entropy-count in tests/syscalls.scm on powerpc64le-linux. * guix/build/syscalls.scm (RNDADDTOENTCNT): When %host-type starts with "powerpc64le", set this to #x80045201. Otherwise, set it to #x40045201 as before. Chris Marusich
2021-03-23syscalls: Fix clone on powerpc64le-linux....This makes the clone procedure work correctly and fixes some test failures on powerpc64le-linux, including tests/containers.scm. * guix/build/syscalls.scm (clone): Add an entry for ppc64le. Chris Marusich
2021-03-15syscalls: mounts: Fix a matching bug....On some systems, the columns in /proc/self/mountinfo look like this: 23 28 0:21 / /proc rw,nosuid,nodev,noexec,relatime shared:11 - proc proc rw Before this change, the mounts procedure was written with the assumption that the type and source could always be found in columns 8 and 9, respectively. However, the proc(5) man page explains that there can be zero or more optional fields starting at column 7 (e.g., "shared:11" above), so this assumption is false in some situations. * guix/build/syscalls.scm (mounts): Update the match pattern to use ellipsis to match zero or more optional fields followed by a single hyphen. Remove the trailing ellipsis, since multiple ellipses are not allowed in the same level. The proc(5) man page indicates that there are no additional columns, so it is probably OK to match an exact number of columns at the end like this. Chris Marusich
2021-03-10syscalls: Define the ST_* constants and add 'statfs-flags->mount-flags'....* guix/build/syscalls.scm (linux?): New variable. (define-statfs-flags): New macro.

Regression introduced in 0d371c633f7308cfde2432d6119d386a5c63198c. * guix/build/syscalls.scm (write-socket-address!) (read-socket-address): Use 'string-contains' instead of 'string-suffix?'. Signed-off-by: Ludovic Courtès <ludo@gnu.org> Jesse Dowell
2020-05-15syscalls: Adjust 'sockaddr-in', 'sockaddr-in6' structs for the Hurd....* guix/build/syscalls.scm (sockaddr-in,sockaddr-in6): Rename to ... (sockaddr-in/linux, sockaddr-in6/linux): ... this.

2020-05-07syscalls: Add ioctl flags for the Hurd....Use #include <stdio.h> #include <net/if.h> #include <hurd/ioctl.h> int main () { printf ("SIOCSIFFLAGS #x%x\n", SIOCSIFFLAGS); printf ("SIOCGIFADDR #x%x\n", SIOCGIFADDR); printf ("SIOCSIFADDR #x%x\n", SIOCSIFADDR); printf ("SIOCGIFNETMASK #x%x\n", SIOCGIFNETMASK); printf ("SIOCSIFNETMASK #x%x\n", SIOCSIFNETMASK); #if 0 printf ("SIOCADDRT #x%x\n", SIOCADDRT); printf ("SIOCDELRT #x%x\n", SIOCDELRT); #endif } to fill in some blanks. Adding and removing route apparently not supported. * guix/build/syscalls.scm (SIOCSIFFLAGS SIOCGIFADDR, SIOCSIFADDR, SIOCGIFNETMASK, SIOCSIFNETMASK): Jan (janneke) Nieuwenhuizen
2020-05-05syscalls: 'define-c-struct' supports cross-compilation....Reported by Jan (janneke) Nieuwenhuizen <janneke@gnu.org>. Before that, we'd always use the 'sizeof' and 'alignof' value obtained from the host at macro-expansion time. * guix/build/syscalls.scm (sizeof*, alignof*): When the target word size differs from the host word size, emit a call to 'sizeof'/'alignof'. Ludovic Courtès
2020-04-20syscalls: Fix Linux detection in 'readdir*'....* guix/build/syscalls.scm (readdir*): Fix Linux detection for `arm-unknown-linux-gnueabihf'. Julien Lepiller
2020-04-16syscalls: 'readdir*' chooses between the Linux and Hurd code at run time....Partly fixes <https://bugs.gnu.org/40574>. Reported by Jan Nieuwenhuizen <janneke@gnu.org>. Previously, we'd choose at expansion time whether to use the Hurd or the Linux variant, taking the cross-compilation target into account. This would lead to the wrong decision when (guix build syscalls) is evaluated while we're cross-compiling to GNU/Hurd. This is a followup to 1ab9e483391f8b62b873833ea71cb0074efa03e7. * guix/build/syscalls.scm (define-generic-identifier) (read-dirent-header, %struct-dirent-header, sizeof-dirent-header): Remove.

2019-07-19syscalls: 'define-as-needed' does not re-export local variables....Fixes <https://bugs.gnu.org/36723>. Reported by Timothy Sample <samplet@ngyro.com>. * guix/build/syscalls.scm (define-as-needed): Rewrite to use lower-level module primitives; define VARIABLE only if it's not already defined to avoid "re-exporting local variable" error. Ludovic Courtès
2019-07-15syscalls: Use 'define-as-needed' for 'AT_' constants introduced in Guile 2.2.5....* guix/build/syscalls.scm (AT_FDCWD, AT_SYMLINK_NOFOLLOW, AT_REMOVEDIR) (AT_SYMLINK_FOLLOW, AT_NO_AUTOMOUNT, AT_EMPTY_PATH): Define using 'define-as-needed'. Ludovic Courtès
