Bug #: 15521
Summary: real-time signals DO NOT delivered starting with the
lowest-numbered signal.
Product: glibc
Version: 2.15
Status: NEW
Severity: normal
Priority: P2
Component: libc
AssignedTo: unassigned@sourceware.org
ReportedBy: 1533963612@qq.com
CC: drepper.fsp@gmail.com
Classification: Unclassified
Created attachment 7040
--> http://sourceware.org/bugzilla/attachment.cgi?id=7040
compile it using -std=c99 option
Assume parent send 3 signals from SIGRTMAX to SIGRTMAX - 2, each signal sends 3
times, the child would recv the signal as order SIGRTMAX - 2 to SIGRTMAX, since
the lowest-numbered should delivered first, and each same number signal deliver
as FIFO order, but the result is:
-----parent send-----
sent 64, val = 1
sent 64, val = 2
sent 64, val = 3
sent 63, val = 1
sent 63, val = 2
sent 63, val = 3
sent 62, val = 1
sent 62, val = 2
sent 62, val = 3
-----child recv-----
recv 64, val = 1
recv 64, val = 2
recv 64, val = 3
recv 63, val = 1
recv 63, val = 2
recv 63, val = 3
recv 62, val = 1
recv 62, val = 2
recv 62, val = 3
we see that the same number signal deliver in rigth sequence (FIFO), but
different signal DO NOT delivered in lowest number first, in this case, should
signal 62 first, and 64 last.

Signal delivery is the business of the kernel. Please report that to
linux-kernel@vger.kernel.org.
