* execve: disallow argc == 0Kyle Evans2022-02-101-1/+4
| | | | | | | | | | | | | | | | | | | | The manpage has contained the following verbiage on the matter for just under 31 years: "At least one argument must be present in the array" Previous to this version, it had been prefaced with the weakening phrase "By convention." Carry through and document it the rest of the way. Allowing argc == 0 has been a source of security issues in the past, and it's hard to imagine a valid use-case for allowing it. Toss back EINVAL if we ended up not copying in any args for *execve(). The manpage change can be considered "Obtained from: OpenBSD" (cherry picked from commit 773fa8cd136a5775241c3e3a70f1997633ebeedf) (cherry picked from commit c9afc7680f3e1f0510518de9de4264553a31aade)

* Document EINTEGRITY errors for many system calls.John Baldwin2020-03-301-1/+3
| | | | | | | | | | | | | | | | | | | EINTEGRITY was previously documented as a UFS-specific error for mount(2). This documents EINTEGRITY as a filesystem-independent error that may be reported by the backing store of a filesystem. While here, document EIO as a filesystem-independent error for both mount(2) and posix_fadvise(2). EIO was previously only documented for UFS for mount(2).

| | | | | | | | | | | | Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

* Fix exec_imgact_shell()'s handling of two error cases: (1) Previously, ifAlan Cox2010-09-211-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | the first line of a script exceeded MAXSHELLCMDLEN characters, then exec_imgact_shell() silently truncated the line and passed on the truncated interpreter name or argument. Now, exec_imgact_shell() will fail and return ENOEXEC, which is the commonly used errno among Unix variants for this type of error. (2) Previously, exec_imgact_shell()'s check on the length of the interpreter's name was ineffective. In other words, exec_imgact_shell() could not possibly fail and return ENAMETOOLONG. The reason being that the length of the interpreter name had to exceed MAXSHELLCMDLEN characters in order that ENAMETOOLONG be returned. But, the search for the end of the interpreter name stops after at most MAXSHELLCMDLEN - 2 characters are scanned. (In the end, this particular error is eventually discovered outside of exec_imgact_shell() and ENAMETOOLONG is returned. So, the real effect of this second change is that the error is detected earlier, in exec_imgact_shell().) Update the definition of MAXINTERP to the actual limit on the size of the interpreter name that has been in effect since r142453 (from 2005).
