Package: src:cpm Version: 0.28-1 Severity: serious Tags: upstream patch Justification: fails to build from source (but built successfully in the past)
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 cpm fails to build from source [1] on SPARC and SPARC64 do to upstream commit 2ba8958a7c. As that commit was needed to build on kFreeBSD, my guess is that a check should be implemented to see if PT_SYSCALL is defined and if not use PTRACE_SYSCALL. Be aware, I have no idea what I am doing code-wise here, but the package builds on SPARC (porterbox) with the attached patch applied.

Description: cpm fails to build on SPARC as PT_ATTACH/PT_SYSCALL is not available The original upstream implementation used PTRACE_ATTCACH/PTRACE_SYSCALL but that FTBFS on kFreeBSD. So apperently we need to check what we have Author: Paul Gevers <elb...@debian.org> Comment: Upstream commit is https://github.com/comotion/cpm/commit/2ba8958a7c935d96b4db183b70f6747ca8151b02 diff --git a/security.c b/security.c index 4735636..7e4b6b2 100644 --- a/security.c +++ b/security.c @@ -521,14 +521,22 @@ int initSecurity(int* max_mem_lock, int* memory_safe, int* ptrace_safe, } #endif +#if defined(PT_ATTACH) if (ptrace(PT_ATTACH, p0, 0, 0) != 0) { +#else + if (ptrace(PTRACE_ATTACH, p0, 0, 0) != 0) { +#endif // someone is already attached to us; shoot the parent in the head fprintf(stderr, "Can't attach to parent!\n"); kill(p0, SIGKILL); _exit(1); } while (1) { +#if defined(PT_SYSCALL) if(ptrace(PT_SYSCALL, p0, 0, 0) == 0) +#else + if(ptrace(PTRACE_SYSCALL, p0, 0, 0) == 0) +#endif waitpid(p0, &status, 0); if(errno == ESRCH && kill(p0, 0) == -1) exit(0); // parent is dead
