2025-02-11lib: crash handlers must be allowed on threadsDavid Lamparter
Blocking all signals on non-main threads is not the way to go, at least the handlers for SIGSEGV, SIGBUS, SIGILL, SIGABRT and SIGFPE need to run so we get backtraces. Otherwise the process just exits. Signed-off-by: David Lamparter <equinox@opensourcerouting.org> (cherry picked from commit 13a6ac5b4ca8fc08b348f64de64a787982f24250)
2023-03-24*: Convert event.h to frrevent.hDonald Sharp
We should probably prevent any type of namespace collision with something else. Signed-off-by: Donald Sharp <sharpd@nvidia.com>
2023-03-24*: Convert `struct event_master` to `struct event_loop`Donald Sharp
Let's find a better name for it. Signed-off-by: Donald Sharp <sharpd@nvidia.com>
2023-03-24*: Convert struct thread_master to struct event_master and it's ilkDonald Sharp
Convert the `struct thread_master` to `struct event_master` across the code base. Signed-off-by: Donald Sharp <sharpd@nvidia.com>
2023-03-24*: Rename thread.[ch] to event.[ch]Donald Sharp
This is a first in a series of commits, whose goal is to rename the thread system in FRR to an event system. There is a continual problem where people are confusing `struct thread` with a true pthread. In reality, our entire thread.c is an event system. In this commit rename the thread.[ch] files to event.[ch]. Signed-off-by: Donald Sharp <sharpd@nvidia.com>
2023-02-09*: auto-convert to SPDX License IDsDavid Lamparter
Done with a combination of regex'ing and banging my head against a wall. Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
2021-11-11*: Convert quagga_signal_X to frr_signal_XDonald Sharp
Naming functions/data structures more appropriately for the project we are actually in. Signed-off-by: Donald Sharp <sharpd@nvidia.com>
2020-10-26lib: add sigevent_check apiMark Stapp
Add an api that blocks application-handled signals (SIGINT, SIGTERM, e.g.) then tests whether any signals have been received. This helps to manage a race between signal reception and the poll call in the main event loop. Signed-off-by: Mark Stapp <mjs@voltanet.io>
2019-02-11lib: add extern "C" {} blocks to all libfrr headersRenato Westphal
These are necessary to use functions defined in these headers from C++. Signed-off-by: David Lamparter <equinox@diac24.net> Signed-off-by: Renato Westphal <renato@opensourcerouting.org>
2017-07-17*: reindentreindent-master-afterwhitespace / reindent
indent.py `git ls-files | pcregrep '\.[ch]$' | pcregrep -v '^(ldpd|babeld|nhrpd)/'` Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
2017-05-15*: make consistent & update GPLv2 file headersDavid Lamparter
The FSF's address changed, and we had a mixture of comment styles for the GPL file header. (The style with * at the beginning won out with 580 to 141 in existing files.) Note: I've intentionally left intact other "variations" of the copyright header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing. Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
2012-10-25*: use array_size() helper macroBalaji.G
Use the array_size() helper macro. Replaces several instances of local macros with the same definition. Reviewed-by: Scott Feldman <sfeldma@cumulusnetworks.com> Signed-off-by: David Lamparter <equinox@opensourcerouting.org>

* (general) extern and static'ification of functions in code and header. Cleanup any definitions with unspecified arguments. Add casts for callback assignments where the callback is defined, typically, as passing void *, but the function being assigned has some other pointer type defined as its argument, as gcc complains about casts from void * to X* via function arguments. Fix some old K&R style function argument definitions. Add noreturn gcc attribute to some functions, as appropriate. Add unused gcc attribute to some functions (eg ones meant to help while debugging) Add guard defines to headers which were missing them. * command.c: (install_node) add const qualifier, still doesnt shut up the warning though, because of the double pointer. (cmp_node) ditto * keychain.c: (key_str2time) Add GET_LONG_RANGE() macro, derived fromn vty.h ones to fix some of the (long) < 0 warnings. * thread.c: (various) use thread_empty (cpu_record_hash_key) should cast to uintptr_t, a stdint.h type * vty.h: Add VTY_GET_IPV4_ADDRESS and VTY_GET_IPV4_PREFIX so they removed from ospfd/ospf_vty.h * zebra.h: Move definition of ZEBRA_PORT to here, to remove dependence of lib on zebra/zserv.h

* sigevent.c: (quagga_signal_handler) add a global caught flag, set the flags to a constant rather increment to be kinder. (quagga_sigevent_process) new function, to do core of what quagga_signal_timer did. dont block signals at all as sig->caught is volatile sig_atomic_t and should be safe to access from signal and normal contexts. The signal blocking is unneeded paranoia, but is left intact under an ifdef, should some platform require it. Check global caught flag before iterating through array. (quagga_signal_timer) nearly everything moved to quagga_sigevent_process. Left in under ifdef, in case some platform could use a regular timer check for signals. * sigevent.h: quagga_sigevent_process declaration. * thread.c: (thread_fetch) check for signals at beginning of scheduler loop, check for signals if select returns EINTR.

* sigevent.{c,h}: New files, implement event handled signals. see signal_init() in sigevent.h.
