* util: introduce get_finfo_for_dev functionMasatake YAMATO2023-02-192-7/+47
| | | | | | | | | | | | | | | | printdev() function does two things: it first obtains the information about the given fd and then prints it. Introduce get_finfo_for_dev() to implement the first part of printdev(). struct finfo is a new data structure for keeping information passed from get_finfo_for_dev() to printdev(). * src/defs.h (struct finfo): New data structure. * src/utils.c (get_finfo_for_dev): New function derived from printdev. (printdev): Use it. Signed-off-by: Masatake YAMATO <yamato@redhat.com> Signed-off-by: Dmitry V. Levin <ldv@strace.io>

* strace: declare nflag variable as staticDmitry V. Levin2023-02-151-1/+1

* hppa: Fix pc.test testcase on hppa architectureHelge Deller2023-01-291-2/+3
| | | | | | | | | | | | | | On hppa the lowest 2 bits of an address encodes the (parisc-specific) address space in which a program runs. For userspace processes the space number is 3, which is why an instruction at e.g. 0x100 shows up in the address registers as 0x103. This behaviour is different than on other architectures, which is why the pc.test testcase fails on hppa. Fix the testcase by simply dropping the last nibble of the address when comparing the output, e.g. search for "0x10?" instead of "0x100". Signed-off-by: Helge Deller <deller@gmx.de>
* hppa: Drop special handling of fanotify syscalls on pariscHelge Deller2023-01-292-9/+0
| | | | | | | | The fanotify syscall in the parisc kernel has been fixed by Linux kernel commit v3.16-rc5~6^2~1 and now behaves like the other architectures, so drop the special workaround for hppa. Signed-off-by: Helge Deller <deller@gmx.de>
* hppa: Fix display of mask for rt_sigreturn syscallHelge Deller2023-01-292-8/+37
| | | | | | | | | | | | | | | | | | | Fix FUNC_GET_RT_SIGFRAME_ADDR to return correct address to the sigframe so that the mask can be shown for the rt_sigreturn syscall. This patch cleans up and simplifies the address calculation when running on Linux kernels < 5.18, where the signal trampoline code was stored in the executable stack. With kernel 5.18 we added a VDSO with the trampoline code, could drop the neccessarity of an executable stack and provided the offset to the ucontext of the rt_sigframe struct for gdb and to simplify the calculation sigframe address. With this patch the rt_sigreturn.gen.test passes for 5.16 and 6.1 kernels on hppa. Signed-off-by: Helge Deller <deller@gmx.de>
* hppa: Disable workaround for hppa in syscall number tamperingHelge Deller2023-01-291-1/+1
| | | | | | | | | | | | This basically disables the workaround added by commit ce494f63d2 ("hppa: workaround kernel bug in syscall number tampering"). It's not needed any longer and has been fixed in upstream kernels by Linux kernel commit v5.0-rc8~9^2~1. Basically the remaining part of that commit could go as well, since hppa was the only user.

* hppa: Switch to getregset call on hppaHelge Deller2023-01-291-1/+1
| | | | | | | | | PTRACE_GETREGSET support was introduced in the parisc kernel by Linux kernel commit v4.7-rc1~58^2~10. This fixes the tampering of syscall return values. Signed-off-by: Helge Deller <deller@gmx.de>
* ci: Add missing permission `security-events`Jan Macku2023-01-261-0/+3
| | | | | | | | | | Differential ShellCheck requires permission `security-events: write` to successfully upload the SARIF file to GitHub. This permission might be optional for some repositories since they allow all permissions for all workflows in settings. But I wouldn't advise this setting since the best security practice is to allow only a minimal set of required permissions.
