Bug ID: 106300
Summary: RFE: analyzer support for more ways of obtaining an
open file descriptor
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: analyzer
Assignee: dmalcolm at gcc dot gnu.org
Reporter: dmalcolm at gcc dot gnu.org
Blocks: 106003
Target Milestone: ---
Currently -fanalyzer special-cases "open" for obtaining a possibly-open file
descriptor (in sm-fd.cc).
We should probably support other ways of obtaining possibly-open file
descriptors, either by special-casing them, or via some new attribute:
creat()
https://www.man7.org/linux/man-pages/man3/creat.3p.html
pipe() and friends:
int pipe(int pipefd[2]);
int pipe2(int pipefd[2], int flags);
https://www.man7.org/linux/man-pages/man2/pipe.2.html
dup() and friends
covered in bug 106298
fcntl()
https://man7.org/linux/man-pages/man2/fcntl.2.html
(though that's probably a deep rabbit-hole that we may not want to go down)
socket()
https://www.man7.org/linux/man-pages/man3/socket.3p.html
