search for: xrealloc

I have a package on CRAN now (corpus-0.3.1) that is currently failing tests on Linux, but passing on all other architectures: https://cran.r-project.org/web/checks/check_results_corpus.html I believe that the issue arrises from a namespace class between "xrealloc", which my package provides for internal use, but which R also seems to provide (possibly as part of TRE in src/extra/tre/xmalloc.c). It looks like my package is not picking up my custom xrealloc, but using an xrealloc provided by R. Besides the fact that I am linking to the wrong xrealloc...

I've done a bit more investigation into this issue. Here is my current understanding of the situation: 1.

Hi, In ssh_krl_from_blob(), krl.c:984, /* Record keys used to sign the KRL */ xrealloc(ca_used, nca_used + 1, sizeof(*ca_used)); ca_used[nca_used++] = key; The result of `xrealloc' is never assigned to `ca_used', which remains a null pointer. Will ca_used[...] crash?. Did I miss anything? Thanks. - xi

Hi. One thing that people seem to want to do with PAM is to deny a login immediately without interacting but return a message to the user. (Some platforms implement, eg, /etc/nologin via PAM this way.) Currently, sshd will just deny the login and the user will not be told why. Attached it a patch that return a keyboard-interactive packet with the message in the "instruction"
