* libpam_misc: use sig_atomic_t instead of intTobias Stoeckmann2023-12-051-1/+1
| | | | | | | Technically it's identical on pretty much all available systems, but let's follow C specifications. Signed-off-by: Tobias Stoeckmann <tobias@stoeckmann.org>
* treewide: do not cast calloc/malloc/reallocTobias Stoeckmann2023-11-121-2/+1
| | | | | | | It is not required to cast the results of calloc, malloc, realloc, etc. Signed-off-by: Tobias Stoeckmann <tobias@stoeckmann.org>

* pam_misc: make length of misc_conv() configurableJeff Squyres2021-06-141-1/+1
| | | | | | | | Add --with-misc-conv-bufsize=<number> option to configure to allow a longer buffer size for libpam_misc's misc_conv() function (it still defaults to 512 bytes). Signed-off-by: Jeff Squyres <jsquyres@cisco.com>
* misc_conv: Flush the terminal input after the password is readTomas Mraz2021-04-121-2/+2
| | | | | | | Fixes #347 * libpam_misc/misc_conv.c (read_string): Use TCSAFLUSH instead of TCSADRAIN when resetting the terminal echo state
* misc_conv: fix potential information leak on error pathDmitry V. Levin2020-07-021-1/+3
| | | | | * libpam_misc/misc_conv.c (read_string): Clear the stack buffer from data read earlier from stdin in case of a read error.
* misc_conv: fix potential stack buffer overflowikerexxe2020-07-011-1/+1
| | | | | | | | [ldv: rewrote commit message] * libpam_misc/misc_conv.c (read_string): Use _pam_overwrite_n instead of _pam_overwrite to clear stack buffer "line" because the latter does not have to be null-terminated.
* misc_conv: remove redundant checkDmitry V. Levin2020-06-301-1/+1
| | | | | * libpam_misc/misc_conv.c (read_string): Remove redundant nc > 0 check as it has already been tested in the previous condition.
* Fix various typos found using codespell toolDmitry V. Levin2020-03-281-1/+1

* misc_conv: Use PAM_MAX_RESP_SIZE to limit the length of the inputTomas Mraz2020-02-241-1/+1

* libpam_misc: fix an inconsistency in handling memory allocation errorsDmitry V. Levin2014-01-221-1/+5
| | | | | | | | | | | | When misc_conv fails to allocate memory for pam_response array, it returns PAM_CONV_ERR. However, when read_string fails to allocate memory for a response string, it loses the response string and silently ignores the error, with net result as if EOF has been read. * libpam_misc/misc_conv.c (read_string): Use strdup instead of x_strdup, the latter is of no benefit in this case. Do not ignore potential memory allocation errors returned by strdup, forward them to misc_conv.
* Fix whitespace issuesDmitry V. Levin2011-10-261-1/+1
| | | | | | Cleanup trailing whitespaces, indentation that uses spaces before tabs, and blank lines at EOF. Make the project free of warnings reported by git diff --check 4b825dc642cb6eb9a060e54bf8d69288fbee4904 HEAD
* Relevant BUGIDs: Debian bug #1708Steve Langasek2007-09-031-2/+1
| | | | | | | | | | | | | Purpose of commit: cleanup (behavior change) Commit summary: --------------- 2007-09-03 Steve Langasek <vorlon@debian.org> * libpam_misc/misc_conv.c: don't block SIGINT in misc_conv; it's perfectly valid to allow the user to interrupt at a prompt. If an application wants prompts to not be interruptable, the application should take responsibility for blocking SIGINT.

* Relevant BUGIDs: 463984Andrew G. Morgan2001-10-111-4/+18
| | | | | | | | | | | | | | Purpose of commit: bugfix Commit summary: --------------- The last fix to the conversation function was less than marginal: it didn't actually work! This second commit adds the all important 'return the user's input' bit! Also added some more D() stuff to pam_misc to help locate the problem and finally cleaned up the Makefile in the examples/ directory. I used xsh to do the testing.

| | | | | | | | | | | | | | Purpose of commit: autoconf support for Linux-PAM Commit summary: --------------- This is a merge of the autoconf support that was developed against a 0-72 branch. [Note, because CVS has some issues, this is actually only 95% of the actual commit. The other files were actually committed when the preparation branch Linux-PAM-0-73pre-autoconf was updated. Hopefully, this will complete the merge.]
