>Description: The Linux executable of the InstallJammer multiplatform GUI installer program (http://www.installjammer.com/) fails to start on a recent 8-STABLE (amd64). A second system with an 8-STABLE kernel built with sources from January runs the program just fine. $ file ./InstallJammer-1.2.14-Linux-x86-Install ./InstallJammer-1.2.14-Linux-x86-Install: ELF 32-bit LSB executable, Intel 80386, version 1 (GNU/Linux), statically linked, stripped $ sysctl compat.linux.osrelease compat.linux.osrelease: 2.6.16 $ pkg_info -qo linux_base\* emulators/linux_base-f10 $ ktrace ./InstallJammer-1.2.14-Linux-x86-Install PROT_EXEC|PROT_WRITE failed. $ linux_kdump -f ktrace.out 27433 ktrace RET linux_brk 0 27433 ktrace CALL linux_olduname(0x7fffffffe8e7,0x7fffffffe630,0x7fffffffe640) 27433 ktrace NAMI "./InstallJammer-1.2.14-Linux-x86-Install" 27433 InstallJammer-1.2.1 RET linux_olduname 0 27433 InstallJammer-1.2.1 CALL linux_mmap(0xffffd7ac) 27433 InstallJammer-1.2.1 RET linux_mmap -1 errno 22 Invalid argument 27433 InstallJammer-1.2.1 CALL write(0x2,0xc547d6,0x1d) 27433 InstallJammer-1.2.1 GIO fd 2 wrote 29 bytes "PROT_EXEC|PROT_WRITE failed.

Reverting the changes in this MFC http://svn.freebsd.org/viewvc/base?view=revision&revision=206602 lets me run the program without problems. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted: _______________________________________________ freebsd-bugs@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
