* Revert "syscalls: 'terminal-dimension' ignores EPERM."Tobias Geerinckx-Rice2021-07-07
| | | | | This reverts commit 17a102332a253f0e3b1f511fa7bda2094264a77c. See <https://github.com/koverstreet/bcachefs/pull/277>.
* syscalls: Fix RNDADDTOENTCNT on powerpc64le-linux.Chris Marusich2021-03-23
| | | | | | | | | 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.
* syscalls: Fix clone on powerpc64le-linux.Chris Marusich2021-03-23
| | | | | | | 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.
* syscalls: mounts: Fix a matching bug.Chris Marusich2021-03-15
| | | | | | | | | | | | | | | | | | 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.
* syscalls: Define the ST_* constants and add 'statfs-flags->mount-flags'.Ludovic Courtès2021-03-10
| | | | | | | | | * guix/build/syscalls.scm (linux?): New variable. (define-statfs-flags): New macro.

* syscalls: Adjust 'sockaddr-in', 'sockaddr-in6' structs for the Hurd.Jan (janneke) Nieuwenhuizen2020-05-15
| | | | | | | | | | * guix/build/syscalls.scm (sockaddr-in,sockaddr-in6): Rename to ... (sockaddr-in/linux, sockaddr-in6/linux): ... this. Rename introduced bindings as well. (write-socket-address!/linux,read-socket-address/linux): Rename from (write-socket-address!, read-socket-address): ... new switches between those and ...

* syscalls: Add ioctl flags for the Hurd.Jan (janneke) Nieuwenhuizen2020-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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):
* syscalls: 'define-c-struct' supports cross-compilation.Ludovic Courtès2020-05-05
| | | | | | | | | | 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'.
* syscalls: Fix Linux detection in 'readdir*'.Julien Lepiller2020-04-20
| | | | | * guix/build/syscalls.scm (readdir*): Fix Linux detection for `arm-unknown-linux-gnueabihf'.
* syscalls: 'readdir*' chooses between the Linux and Hurd code at run time.Ludovic Courtès2020-04-16
| | | | | | | | | | | | | | | | | | | | 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. (readdir*): Rename to... (readdir-procedure): ... this, and add parameters. (readdir*): Define as a call to 'readdir-procedure' as a function of %HOST-TYPE.

| | | | | | | * guix/build/syscalls.scm (call-with-file-lock) (call-with-file-lock/no-wait): Initialize PORT in the 'dynamic-wind' "in" handler. This allows us to re-enter a captured continuation and have the lock grabbed anew.
* syscalls: Pass the right 'throw' arguments in 'call-with-file-lock/no-wait'.Ludovic Courtès2020-01-19
| | | | | | | | Reported by Matt Wette <matt.wette@gmail.com> in <https://bugs.gnu.org/39194>. * guix/build/syscalls.scm (call-with-file-lock/no-wait): When re-throwing, pass KEY in addition to ARGS.

| | | | | | | | | 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.
* syscalls: Use 'define-as-needed' for 'AT_' constants introduced in Guile 2.2.5.Ludovic Courtès2019-07-15
