Subject: [PATCH 4.9 23/29] modpost: fix section mismatch check for exported init/exit sections
Date: Thu, 30 Jun 2022 15:46:23 +0200 [thread overview]
Message-ID: <20220630133231.881578142@linuxfoundation.org> (raw)
In-Reply-To: <20220630133231.200642128@linuxfoundation.org>
From: Masahiro Yamada <masahiroy@kernel.org>
commit 28438794aba47a27e922857d27b31b74e8559143 upstream.
Since commit f02e8a6596b7 ("module: Sort exported symbols"),
EXPORT_SYMBOL* is placed in the individual section ___ksymtab(_gpl)+<sym>
(3 leading underscores instead of 2).
Since then, modpost cannot detect the bad combination of EXPORT_SYMBOL
and __init/__exit.
Fix the .fromsec field.
Fixes: f02e8a6596b7 ("module: Sort exported symbols")
