This commit adds a patch to ConnMan that modifies the version scripts (src/connman.ver and vpn/vpn.ver) to avoid hiding implementation-reserved symbols (such as _IO_stdin_used). Previously, using 'local: *;' in the version script caused glibc's libio to misdetect the libc version, resulting in a crash when printing to stdout (e.g., running 'connmand --help') on PowerPC. The new patch changes 'local: *;' to 'local: [!_]*;', following the recommendation in glibc bug 17908 (https://sourceware.org/bugzilla/show_bug.cgi?id=17908). This ensures that symbols starting with an underscore are not hidden, allowing libio to correctly detect the libc version and preventing the crash.

Subject: [PATCH] connman, vpn: avoid hiding implementation-reserved symbols
|
|
|
|
When using 'local: *;' in the version script, all symbols, including those
|
|
reserved for the implementation (such as _IO_stdin_used), are hidden. This
|
|
causes glibc's libio to misdetect the libc version, leading to a crash when
|
|
glibc prints to stdout (e.g., with connmand --help) on PowerPC.
|
|
|
|
Change 'local: *;' to 'local: [!_]*;' to avoid hiding symbols starting with an
|
|
underscore, as recommended in glibc bug 17908
|
|
(https://sourceware.org/bugzilla/show_bug.cgi?id=17908). This ensures libio can
|
|
correctly detect the libc version and prevents the crash.
