Bootloader fork rebase:
- Base changed from 0.1.0 pre-patched archive to upstream 1.0.0 tag (c7eeb9f)
- Applied 0001-redbear-local-forks.patch (Cargo.toml crate path redirects)
- Applied fix-uefi-alloc-panic.patch equivalents (4 panic!() -> graceful
error handling in src/main.rs)
- Applied P5-live-preload-cap-1gib.patch (1 GiB cap on live image preload)
- Skipped: P0 GPT partition scan (requires new module + integration),
P1 timeout/default-resolution, P2 live preload guard (subsumed by
panic fixes + cap), P3 live image safe read, P4 large ISO boot,
redox.patch — to be applied in dedicated rebase session.
firmware-loader/Cargo.toml: version 0.1.0 -> 0.3.0 (sync with other
Red Bear custom crates which are at 0.3.0).
fork-upstream-map.toml: bootloader back from PENDING_REBASE to 1.0.0
since the partial rebase matches upstream 1.0.0 content.
fork-upstream-map.toml: base restored to 'main' tracked (was correctly
tracked by build-redbear.sh).

/* Set up ACTION so that it is invoked on C stack overflow and on other,
|
|
stack-unrelated, segmentation violation.
|
|
Return -1 (setting errno) if this cannot be done.
|
|
|
|
When a stack overflow or segmentation violation occurs:
|
|
1) ACTION is called. It is passed an argument equal to
|
|
- 0, for a stack overflow,
|
|
- SIGSEGV, for a segmentation violation that does not appear related
|
|
to stack overflow.
|
|
On many platforms the two cases are hard to distinguish; when in doubt,
|
|
zero is passed.
|
|
2) If ACTION returns, a message is written to standard error, and the
|
|
program is terminated: in the case of stack overflow, with exit code
|
|
exit_failure (see "exitfail.h"), otherwise through a signal SIGSEGV.
|
|
|
|
A null ACTION acts like an action that does nothing.
|
|
|
|
Restrictions:
|
|
- ACTION must be async-signal-safe.
|
|
- ACTION together with its callees must not require more than 64 KiB of
|
|
stack space.
|
|
- ACTION must not create and then invoke nested functions
|
|
<https://gcc.gnu.org/onlinedocs/gcc/Nested-Functions.html>, because
|
|
this implementation does not guarantee an executable stack.
|
|
- ACTION should not call longjmp, because this implementation does not
|
|
guarantee that it is safe to return to the original stack.
|
|
|
|
This function may install a handler for the SIGSEGV signal or for the SIGBUS
|
|
signal or exercise other system dependent exception handling APIs. */
