--- Begin Message ---Package: dietlibc-dev Version: 0.29-8 Severity: normal Herbert Poetzl reported the following problem with dietlibc on hppa/parisc machines: syscalls.s/_llseek.S defines the llseek function as direct branch/call to the unified syscall wrapper (which I think is wrong too, but to that later) now, on hppa/parisc the calling convention uses r26-r23 for the first four arguments, the rest is spilled onto the stack. however the Linux kernel passes the first six arguments in the registers r26-r21. as the llseek syscall takes five arguments, this leads to random arguments for the r22 (whence argument) and strange failures like this: _llseek(3, 0, 0xc00202d0, 0x4047f444 /* SEEK_??? */) = -1 EINVAL (Invalid argument) with the following test code int main(int argc, char *argv[]) { int fd, ret; loff_t lpos; char *name = argv[1]; fd = open(name, O_RDONLY); ret = llseek(fd, 0, 0, &lpos, SEEK_END); printf("file %s has length %lld\n", name, (long long)lpos); close(fd); exit(0); } a dirty hack (just to verify that this is true) is to add the following: llseek: + ldw -0x34(%sp), %r22 syscall(_llseek,_llseek) which will load the r22 register with the proper value from the stack ... another issue I found for parisc/hppa is that parisc/unified.S does __unified_syscall: be,l 0x100(%sr2, %r0), %sr0, %r31 nop while the linux kernel says: arch/parisc/kernel/signal.c * We need to be able to restore the syscall arguments (r21-r26) to * restart syscalls. Thus, the syscall path should save them in the * pt_regs structure (it's okay to do so since they are caller-save * registers). As noted below, the syscall number gets restored for * us due to the magic of delayed branching. /* Hooray for delayed branching. We don't have to restore %r20 (the system call number) because it gets loaded in the delay slot of the branch external instruction. */ so the following seems still to be true: The system call number MUST ALWAYS be loaded in the delay slot of the ble instruction, or restarting system calls WILL NOT WORK. a possible 'workaround' would be to use some other register and just 'copy' the syscall number to r20 in the delay slot, also on PIC code r19 has to be saved as it will be clobberd -- System Information: Debian Release: testing/unstable APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (500, 'stable') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.15-1-686-smp Locale: LANG=en_US, LC_CTYPE=en_US (charmap=ISO-8859-1) dietlibc-dev depends on no packages.
