-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi.
This is not a strace only issue, gdb is affected too. This issue (debugger/tracer receiving SIGSTOP) is specific of the latest 2.6.32 linux kernel series release (2.6.32.61), when commit 16365e5badcb314f350c47d4a9be90ed8a61b71a [1] was introduced to fix CVE-2013-0871 [2]. Commit 55436c91652b45be576b91ec96a8d65f6b7447fa [3] fixes this debug/trace issue on mips architecture. Note that this commit was applied only on kernels >= 2.6.34. Kind regards. - --- Notes: [1]: wake_up_process() should be never used to wakeup a TASK_STOPPED/TRACED task [2]: Race condition in the ptrace functionality in the Linux kernel before 3.7.5 allows local users to gain privileges via a PTRACE_SETREGS ptrace system call in a crafted application, as demonstrated by ptrace_death. [3]: mips: use generic ptrace_resume code -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAEBAgAGBQJS2SSIAAoJEEMgiHR4i0Q9tQEIAK0gy8t+4X4S/ZEa3GMhGQeN lNw9un326sViSSVAwzhsD/8tLCVHgGcfqU5k/n8udG97bHZyiAs2DUYW58wL8WGm IJXLdKPTFMcEQrVSkYmb2Jch29Sb6lV8XGB/cjvsGprbuVTzsXTVwkS4IkG39elS M+cKj6SfuuHVRjkqtOL4Pt0moGkALyrs7KO9EZcf+dofvGdaP0/V0ffcyT0CN1+w CS1ri983EtiNV17p3Kw6dxVNa20f74KSnIGgYUlYu9qTVNeD60wFfdpnvrAXxkGK Ls9hlsT+oGcUEAFvWwYYy9rR3ItKlUS7Q6rGGWdYcgNgMenxCXvHPbn5hOQlqQk= =5Xht -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ CenturyLink Cloud: The Leader in Enterprise Cloud Services.
