With kernel headers of version 2.6.9, however, inclusion of many kernel headers, for instance, linux/cdrom.h, leads to inclusion of linux/byteorder/*_endian.h. These headers declare functions using types that are hidden when the features.h header from glibc is included. The attached testcase illustrates the problem. To amend this, the conflicting declarations should be disabled when __KERNEL__ macro is not defined. The patch is underway. Steps to Reproduce: Try compiling the attached C source file. Actual Results: Compilation fails. Expected Results: Compilation should succeed. 19458 1 621 mhz 2004-10-27 19:59:56 +0400 Created attachment 621 The testcase C source file 19459 2 622 mhz 2004-10-27 20:01:20 +0400 Created attachment 622 Proposed patch This patch has been tested against: the testcase above; gnome-vfs 2.8.x. 19553 3 rider 2004-11-01 18:46:01 +0300 fixed (2.6.9-alt11) 19590 4 mhz 2004-11-03 13:13:10 +0300 Any chance it goes upstream? 41171 5 ldv 2006-10-06 03:31:52 +0400 The patch in question also breaks build: $ rpmbuild -bc hdparm.spec [...] hdparm.c:1315: warning: implicit declaration of function '__le16_to_cpus' hdparm.c:1315: warning: nested extern declaration of '__le16_to_cpus' cc -o hdparm hdparm.o identify.o hdparm.o: In function `process_dev': hdparm.c:(.text+0x1a4f): undefined reference to `__le16_to_cpus' hdparm.o: In function `main': hdparm.c:(.text+0x3791): undefined reference to `__le16_to_cpus' collect2: ld returned 1 exit status make: *** [hdparm] Error 1 41231 6 vsu 2006-10-10 20:16:03 +0400 Broken patch removed in std26-2.6.16-alt11; let's see what breaks without it... 621 2004-10-27 19:59:56 +0400 2004-10-27 19:59:56 +0400 The testcase C source file kernel-types-conflict.c text/plain 48 mhz I2luY2x1ZGUgPHN5cy90eXBlcy5oPgojaW5jbHVkZSA8bGludXgvY2Ryb20uaD4K 622 2004-10-27 20:01:20 +0400 2004-10-27 20:01:20 +0400 Proposed patch kernel-2.6.9-polluted-endian.patch text/plain 2104 mhz LS0tIGtlcm5lbC1zb3VyY2UtMi42LjkvaW5jbHVkZS9saW51eC9ieXRlb3JkZXIvcGRwX2VuZGlh bi5oLm9yaWctcG9sbHV0ZWQJMjAwNC0xMC0xOSAwMTo1NTozNSArMDQwMAorKysga2VybmVsLXNv dXJjZS0yLjYuOS9pbmNsdWRlL2xpbnV4L2J5dGVvcmRlci9wZHBfZW5kaWFuLmgJMjAwNC0xMC0y NyAxODo0MDoyOCArMDQwMApAQCAtMzAsNiArMzAsOCBAQAogI2luY2x1ZGUgPGxpbnV4L2J5dGVv cmRlci9zd2FiLmg+CiAjaW5jbHVkZSA8bGludXgvYnl0ZW9yZGVyL3N3YWJiLmg+CiAKKyNpZiBk ZWZpbmVkKF9fS0VSTkVMX18pCisKICNkZWZpbmUgX19jb25zdGFudF9odG9ubCh4KSBfX19jb25z dGFudF9zd2FoYjMyKCh4KSkKICNkZWZpbmUgX19jb25zdGFudF9udG9obCh4KSBfX19jb25zdGFu dF9zd2FoYjMyKCh4KSkKICNkZWZpbmUgX19jb25zdGFudF9odG9ucyh4KSBfX19jb25zdGFudF9z d2FiMTYoKHgpKQpAQCAtODMsNiArODUsOCBAQAogI2RlZmluZSBfX2NwdV90b19iZTE2cyh4KSBf X3N3YWIxNnMoKHgpKQogI2RlZmluZSBfX2JlMTZfdG9fY3B1cyh4KSBfX3N3YWIxNnMoKHgpKQog CisjZW5kaWYgLyogX19LRVJORUxfXyAqLworCiAjaW5jbHVkZSA8bGludXgvYnl0ZW9yZGVyL2dl bmVyaWMuaD4KIAogI2VuZGlmIC8qIF9MSU5VWF9CWVRFT1JERVJfUERQX0VORElBTl9IICovCi0t LSBrZXJuZWwtc291cmNlLTIuNi45L2luY2x1ZGUvbGludXgvYnl0ZW9yZGVyL2JpZ19lbmRpYW4u aC5vcmlnLXBvbGx1dGVkCTIwMDQtMTAtMTkgMDE6NTU6MDcgKzA0MDAKKysrIGtlcm5lbC1zb3Vy Y2UtMi42LjkvaW5jbHVkZS9saW51eC9ieXRlb3JkZXIvYmlnX2VuZGlhbi5oCTIwMDQtMTAtMjcg MTg6Mzk6MzYgKzA0MDAKQEAgLTExLDYgKzExLDggQEAKICNpbmNsdWRlIDxsaW51eC90eXBlcy5o PgogI2luY2x1ZGUgPGxpbnV4L2J5dGVvcmRlci9zd2FiLmg+CiAKKyNpZiBkZWZpbmVkKF9fS0VS TkVMX18pCisKICNkZWZpbmUgX19jb25zdGFudF9odG9ubCh4KSAoKF9fZm9yY2UgX19iZTMyKShf X3UzMikoeCkpCiAjZGVmaW5lIF9fY29uc3RhbnRfbnRvaGwoeCkgKChfX2ZvcmNlIF9fdTMyKShf X2JlMzIpKHgpKQogI2RlZmluZSBfX2NvbnN0YW50X2h0b25zKHgpICgoX19mb3JjZSBfX2JlMTYp KF9fdTE2KSh4KSkKQEAgLTEwMSw2ICsxMDMsOCBAQAogI2RlZmluZSBfX2NwdV90b19iZTE2cyh4 KSBkbyB7fSB3aGlsZSAoMCkKICNkZWZpbmUgX19iZTE2X3RvX2NwdXMoeCkgZG8ge30gd2hpbGUg KDApCiAKKyNlbmRpZiAvKiBfX0tFUk5FTF9fICovCisKICNpbmNsdWRlIDxsaW51eC9ieXRlb3Jk ZXIvZ2VuZXJpYy5oPgogCiAjZW5kaWYgLyogX0xJTlVYX0JZVEVPUkRFUl9CSUdfRU5ESUFOX0gg Ki8KLS0tIGtlcm5lbC1zb3VyY2UtMi42LjkvaW5jbHVkZS9saW51eC9ieXRlb3JkZXIvbGl0dGxl X2VuZGlhbi5oLm9yaWctcG9sbHV0ZWQJMjAwNC0xMC0xOSAwMTo1NDozMiArMDQwMAorKysga2Vy bmVsLXNvdXJjZS0yLjYuOS9pbmNsdWRlL2xpbnV4L2J5dGVvcmRlci9saXR0bGVfZW5kaWFuLmgJ MjAwNC0xMC0yNyAxODozODoxMiArMDQwMApAQCAtMTEsNiArMTEsOCBAQAogI2luY2x1ZGUgPGxp bnV4L3R5cGVzLmg+CiAjaW5jbHVkZSA8bGludXgvYnl0ZW9yZGVyL3N3YWIuaD4KIAorI2lmIGRl ZmluZWQoX19LRVJORUxfXykKKwogI2RlZmluZSBfX2NvbnN0YW50X2h0b25sKHgpICgoX19mb3Jj ZSBfX2JlMzIpX19fY29uc3RhbnRfc3dhYjMyKCh4KSkpCiAjZGVmaW5lIF9fY29uc3RhbnRfbnRv aGwoeCkgX19fY29uc3RhbnRfc3dhYjMyKChfX2ZvcmNlIF9fYmUzMikoeCkpCiAjZGVmaW5lIF9f Y29uc3RhbnRfaHRvbnMoeCkgKChfX2ZvcmNlIF9fYmUxNilfX19jb25zdGFudF9zd2FiMTYoKHgp KSkKQEAgLTEwMSw2ICsxMDMsOCBAQAogI2RlZmluZSBfX2NwdV90b19iZTE2cyh4KSBfX3N3YWIx NnMoKHgpKQogI2RlZmluZSBfX2JlMTZfdG9fY3B1cyh4KSBfX3N3YWIxNnMoKHgpKQogCisjZW5k aWYgLyogX19LRVJORUxfXyAqLworCiAjaW5jbHVkZSA8bGludXgvYnl0ZW9yZGVyL2dlbmVyaWMu aD4KIAogI2VuZGlmIC8qIF9MSU5VWF9CWVRFT1JERVJfTElUVExFX0VORElBTl9IICovCg==
